The lesser are those which devide it into two vnequall parts, one bigger, another lesse.
- Of the former sort there are foure, the
- The Æquitor or Æquonoctiall line, is a line drawen iust in the
midst of the earth, from East to West, which compasseth it as a
girdle doth a mans body, and devidith it into two equall parts,
one on the North side, the other on the South The two points in
the earth that are every way farthest distant from it North, &
South are called the Poles of the earth which doe directly stand
vnder the two like points in the Heaven, so called because the
Heaven turnes about vpon them, as the Earth doth in a Globe
that's set in a frame. This circle is of the first & principall
note and vse in Geography, because all measurings for distances
of places and quarters of the Earth are reckoned in it, or from
it. It is called the Æquinoctiall, because when the Sunne in the
Heavens comes to be directly over that circle in the earth, the
daies & nights are of equall length in all parts of the world.
Marriners call it by a kind of excellency, The line. Vpon the
Globe it is easily discerned being drawen bigger then any other
circles from East to West, and with small divisions.
- The Meridian, if a line that is drawen quite crosse the
Æquinoctiall, and passeth through the Poles of the Earth, going
directly North and South. It is called the Meridian, because
when the Sunne stands just over that circle it is Meridies i.d.
noone day. It may be conceaued thus, at noone day, when it is
just twelue a clocke, turne your face towards the South, and then
imagine with your selfe two circles drawen, one in the Heavens,
passing from the North iust over your head through the body of
the Sunne downe to the South, and so round vnder the earth vp
againe to the North Pole. Another vpon the surface of the earth
passing through your feete just vnder the Sunne, and so
compassing the earth round till it meete at your feete againe,
and these are Meridians answering one to another. Now the
Meridian is not one only, as was the Æquinoctiall, but many still
varying according to the place wherein you are, as for example.
At London there is one Meridian, at Oxford another, at
Bristow another, & so along Eastward or Westward. For it is
noone at London sooner then at Oxford, and at Oxford sooner
then at Bristow. Vpon the globe there are many drawen, all
which passe through the poles, and goe North and South, but there
is one more remarkeable then the rest, drawen broad with small
divisions, which runneth through the Canary Ilands, or through
the Ilands of Azores Westward of Spaine, which is counted the
first Meridian in regard of reckoning and measuring of distances
of places one from another; for otherwise there is neither first
nor last in the round earth. But some place must bee appointed
where to beginne the account and those Ilands haue beene thought
fittest, because no part of the World that lay westward was
knowne to the Ancients further then that: and as they began to
reckon there, we follow them. This circle is called in greeke
Μεσημβρινοσ.
- The Horizon is two fold:
- The Sensible or appearing Horizon is the space of the earth so
farre as in an open plaine, or vpon some Hill a man may see round
about him. The brim or edge of the earth further then which you
cannot see, that is the Horizon, or as some call it the
Finitor. Because finet or terminat visum it setts the
limits or bounds to your sight, beyond which nothing can bee
seene vpon the earth. This is greater or lesser, according as the
height of the eye aboue the plaine superficies of the earth, is
more or lesse. The most exact triall hereof is at Sea, where
there are no mountaines nor any vnequall risings of the water to
hinder the sight, as there are at land. For example let (CBAF)
be the superficies of the Sea and let a mans eye bee placed in
(X) aboue the Sea; as the eye stands higher or lower so will
the distance seene be more or lesse, [Sidenote: See Wright of Navigation p.
229.] as if the hight of (XA) be
6 foot which is ordinary the height of a man, the eye looking
from (X) to (B) shall see 2 miles and 3 quarters, if (X) be
20 foote high (BA) will bee fiue miles, if 40 foote 7 miles, if
50 foote 8 miles. So that from the mast of a ship 50 foote
high, a man may see round about at sea 8 miles every way, toward
(BG) and (F). So farre may the water it selfe be seene, but
any high thing on the Water may be seene farther, 16, or 20 miles
according as the height is, as the ship at (C) may be seene
from (X) as far more as it is from (A) to (B). There can be
therefore no certaine quantity and space set downe for this
sensible Horizon, which continually varies according to the
height of the eye aboue the plaine ground or sea. This Horrizon
is not at all painted on the globe nor can be.
- The intelligible or true Horizon is a line which girts the earth
round in the midst, and divides it into two equall parts or
Hæmispheares the vppermost vpon the top & middle point
whereof wee dwell, and that which is vnder vs. Opposite to this
in the Heavens is another Horizon, which likewise cuts the Heaven
into two Hemispheres, the vpper and the lower. Aboue which circle
when any starre or the Sunne is moued, it then riseth vnto vs,
and setteth vnto those that dwell opposite vnto vs, and so on the
contrary, you may conceiue it best thus, if standing vpon a hill,
or some open place, where you may perfectly see the setting of
the Sunne, you marke when the Sun is halfe gone out of your
sight, you may perceiue the body of the Sunne cut in two, as it
were by a line, going along through it, the halfe aboue is yet
seene, that vnderneath is gone out of your sight. This line is
but a peece of the Horrizon, which if you conceiue to be drawen
vpward about the World from the West to the North, and so by East
and South, to West againe you haue the whole Horrizon described.
- This circle is not drawen vpon the body of the globe, because it
is variable; but stands one the outside of it, beeing a broad
circle of wood couered with paper on which are sett the moneths
and days of the yeare, both in the old and new Calender, and also
the 12 signes, and the points of the compasse. All which are
easily discerned by the beholdinge. The vse of this Horizon is
not so much in Geographie as in Astronomie.
- { Sensible or appearing.
- { Intelligible or true.
- The Zodiake is a circle which compasseth the earth like a belt,
crossing the æquator slopewise, not streight as the Meridians
doe. Opposite to it in the Heauens is another circle of the same
name, wherein are the 12. signes, and in which the Sunne keepes
his owne proper course all the yeare long, neuer declining from
it on the one side or other. The vse hereof in Geography is but
litle only to shew what people they are ouer whose heads the
Sunne comes to bee once or twice a yeare; who are all those that
dwell with in 23. degrees of the Aequator; for so much is the
declination, or sloping of the Zodiacke. This circle is also
called the Eclipticke line, because when the Sunne and Moone
stand both in this circle opposite each to other, then there
happens an Eclipse of the Sunne or Mone, vpon a globe it is
easily discerned, by the sloping of it from the Aequator, and the
diuisions of it into 12. parts, and euery of those 12. into 30.
degrees.
- { 1 Æquator.
- The tropickes are two, parallel circles distant on each side of
the Aequator 23. degrees shewing the farthest bounds of the Sunns
declination North or South from the Aequator, or the midest of
heauen. And therefore they are called tropickes a
τρεπωθαι
vertendo, because when the Sunne comes ouer these
lines, hee either turnes away from vs, as in the Summer, or
turnes toward vs againe as in the winter: There are then two of
them vid.
- The Tropicke of Cancer which lies on the North side of the
Aequator, to which when the Sunne comes, it makes the longest day
in Summer.
- The Tropicke of Capricorne, lying Southward of the Aequator, to
which when the Sunne comes, it makes the shortest day in winter.
- The Polar circles are two parallels drawne by the poles of the
Zodiacke compassinge about the poles of the world, being distant
from them euery way 23 degrees. These are two.
- The Articke Circle that compasseth about the North Pole: it is
so called because that in the Heavens (where vnto this in the
earth lies opposite) runs through the constellation of the great
Beare, which in greeke is called αρκτοσ
- The Antarticke circle that compasseth about the South Pole, &
is placed opposite vnto the former.
- To describe an Æquinoctiall planispheare, draw a circle
(ACBD) and inscribe in it two diameters (AB) & (CD) cutting
each other at right angles, and the whole circle into foure
quadrants: each whereof devide into 90. parts, or degrees. The
line (AB) doth fitly represent halfe of the Æquator, as the
line (CD) in which the points (C) & (D) are the two poles,
halfe of the Meridian: for these circles the eye being in a
perpendicular line from the point of concurrence (as in this
projection it is supposed) must needs appeare streight. To draw
the other, which will appeare crooked, doe thus. Lie a rule from
the Pole (C) to every tenth or fift degree of the halfe circle
(ADB) noting in the Æquator (AB) every intersection of it and
the rule. The like doe from the point (B) to the semicircle
(CAD) noting also the intersections in the Meridian (CD) Then
the diameters (CB) and (AB) being drawne out at both ends, as
farre as may suffice, finding in the line (DC) the center of
the tenth division from (A) to (C) and from (B) to (C), &
of the first point of intersection noted in the meridian
frõ
the Æquator towards (C) by a way familiar to Geometricians
connect the three points, and you haue the paralell of 10.
degrees from the Æquator: the like must bee done in drawing the
other paralells on either side, the Æquator; as also in drawing
the Meridians from centers found in the line (AB) in like maner
continued. All which is illustrated by the following diagram.
- To describe a Polar Planisphære, draw a circle (ACBD) on the
center (E) & as before, inscribe in it two diameters (AB) and
(BC) cutting each other at right angles, and the circle into
foure quadrants. Each quadrant being deuided into 90. parts, draw
from euery 5th or 10th of those parts a diameter to the
opposite point: these lines all concurring in the center (E)
being the pole, are as so many Meridians. Next, hauing cutt the
halfe of any one of the former diameters into 9 parts, as (ED)
in the points (FGHIKLMN) draw on the center (E) so many
circles and these represent the paralells of the Globe, being
also here true paralells.
- All these with the former
are easily known
vpõ
the Globe by these
descriptiõs,
& names vsually added vnto
thẽ.
But because maps are of an esier price, & more
cõmon
vse then Globes, it will be needfull to
shew how all these circles, which are drawne most naturally vpon
a round Globe, may also as truly, and profitably for knowledge
and vse be described vpon a plaine paper. Whereby we shall
vnderstand the reason of those lines which We see in the vsuall
Mapps of the world, both how they are drawne, and wherefore they
serue. Vnderstand therefore, that in laying downe the globe vpon
a plaine paper, you must imagine the globe to be cut in two
halfes through the midst, and so to be pressed downe flat to the
paper; as if you should take a hollow dish, and with your hand
squieze the bottom down, till it lie flat vpon a bord, or any
other plaine thing for then will those circles that before were
of equall distance, runne closer together towards the midst.
After this conceit, vniversall Maps are made of two fashions,
according as the globe may be devided two waies, either cutting
quite through by the meridian from North to South, as if you
should cut an apple by the eye and the stalke, or cutting it
through the Æquinoctiall, East and West, as one would divide an
apple through the midst, betweene the eye & the stalke. The
former makes two faces, or hemispheares, the East and the West
hemispheare. The latter makes likewise two Hemispheares, the
North and the South. Both suppositions are good, and befitting
the nature of the globe: for as touching such vniversall maps,
wherein the world is represented not in two round faces, but all
in one square plot, [Sidenote:
Of this Hypothesis see Wrights errors of
navigation.]
the ground wherevpon such descriptions are
founded, is lesse naturall and agreeable to the globe, for it
supposeth the earth to be like a Cylinder (or role of bowling
allies) which imagination, vnlesse it be well qualified, is
vtterly false, and makes all such mappes faulty in the
scituation of places. Wherefore omitting this, we will shew the
description of the two former only, both which are easie to be
done.
- { 2 Meridian.
- { 3 Horizon.
- { 4 Zodiack, or Eclipticke.
- These are the greater circles: the lesser follow; which are all
of one nature, and are called by one generall name: sc.
Parallels, because they are so drawen on each side of the
Aequator, as they are equidistant vnto it euery way. Many of
this kinde are drawne vpon the globe (as is easie to bee seene)
and may bee conceaued to bee drawne vpon the earth: but there are
only two sorts cheifely to bee marked: namely the
- { Tropickes and the
- { Polar circles.
| Of the former sort there are foure, the | { 1 Æquator. |
| { 2 Meridian. |
| { 3 Horizon. |
| { 4 Zodiack, or Eclipticke. |
| The Horizon is two fold: | { Sensible or appearing. |
| { Intelligible or true. |
| | { Tropickes and the |
| { Polar circles. |
CAP. 5.
Of divers Distinctions, and Divisions of the earth.
Next after the Circles of the Earth, wee may not vnfitly handle the seuerall Divisions and distinctions which geographers make of the parts, and inhabitants of the earth. These are many, but wee will briefely runne them ouer.
- The first and most plaine is by the Coasts of the Heauens, and
rising, and Setting of the Sunne, so it is distinguished into the
- East where the Sunne ariseth. Oreins, Ortus
ανατολη.
- West where the Sunne goeth downe. occidens.
- North: betweene both fromwards the Sunne at Noone. Septentrio.
- South: betweene both towards the Sun at Noone. Meridies.
- These foure are called the cheife or Cardinall quarters of the
world. They with the others betweene them are easily knowne but
are of more vse to Mariners then to vs. Wee may rather take
notice of those other names which by Astronomers Geographers
Divines and Poets are giuen vnto them. Who sometime call the East
the right hand part of the world, sometime the West, sometime the
North, & sometime South, the diuersity is noted in these verses,
- The hot or burning Zone (Zona torrida) which containes all
that space of earth, that lieth betwtene the two
Tropicks,
supposed heretofore (but falsly as after experience hath shewed)
to be inhabitable by reason of heat, the Sunne continually lying
ouer some part of it.
- The temperate Zones wherein neither heat nor cold is extreame
but moderate: these are two, one on the North side of the
Aequator, betweene the Articke circle, and the
Tropicke
of
Cancer, another on the South side betweene the
Tropicke
of
Capricorne, and the Antarcticke circle.
- The cold, or Frozen Zones, wherein cold for the most part is
greater then the heat, these likewise are two, one in the North,
betweene the Articke circle, and the North Pole, another on the
South betweene the Antarctick circle and the South Pole. These of
all parts of the earth are worst inhabited, according as
extremity of cold is alwaies a greater enemy to mans body, then
extremity of heat.
- Ad Boream terræ, Sed Coeli mensor ad Austrum,
Præco Dei exortum videt, occasumque Poeta.- Amphiscy (αμφισχιοι)
whose shadow at noone day
fall both waie, so to the North when the Sunne is Southward of
them, & to the South when the Sunne is Northward, and such are
those people that doe dwell in the hot Zone. For the Sunne goes
ouer their heads twice a yeare, once Northward, another time
Southward, when the Sunne is just ouer their heads they are
called Asoy, ασχιοι,
without shadow.
- Heteroscy ('ετεροσχιοι)
whose shadowes doe alwaies
fall one way, namely alwaies towards the North, as those that
dwell in the Northerne temperate Zone, or alwaies to the South,
as those that dwell in the Southerne temperate Zone.
- Periscy (περισχιοι)
whose shadowes goe round about
them, as those people who dwell in the two cold Zones, for as the
Sunne never goes downe to them after he is once vp, but alwaies
round about, so doe their shadowes.
- That is
- Perioeci
(περιοιχοι)
such as dwell round
about the Earth in one and the same paralell, as for
example vnder the Tropicke of Cancer.
- Antoeci
(αντοιχοι)
such as dwell opposite to
the former in another Paralell of the same distance
from the Æquator. As those vnder the Tropicke of
Capricorne.
- Antipodes
(αντιποδεσ)
who dwell iust vnder vs
theire feete opposite to ours.
- Geographers looke to the North, Astronomers to the South.
Priests turne them to the East, & Poets to the West.- Absolutely, and so the
- Longitude or Length of the Earth is its Circuit, and
Extension from East to west,
- Latitude or breadth of it, is the whole Circuit and
Compasse of it from North to South.
- Comparatiuely: comparinge one places scituation with
another, and so the
- Longitud of a place, is the distance of it from the
first Meridian going through the Canary Ilands,
Eastward. Whereby wee know how farre one place lies
East or West from another.
- Latitude of a place, is the distance of it from the
Æquator towards the North or South. Whereby wee know
how farre one Place lies Northward, or Southward of
another.
- This serues for vnderstanding of Authors, wherein any mention is
made of the right or left part of the World, if for example he be
a poet, he means the South by the right hand, the North by the
left: because a poet turnes his face to the West, and so reckons
the quarters of Heauen and Earth.
- The second distinction is by the notable differences of heat
and cold, that are observed on the earth, this is the division of
the Earth by Zones or Girdles, which are parts of the Earth,
wherin heat and cold doe remarkably increase or decrease. Those
Zones are 5.
- They dwell (in Sphæra recta) in a right or streight Spheare who
dwell iust vnder the Æquinoctiall, whose Horizon is paralell to
the Meridians, but cutts the Æquator at right Angles, they dwell
in paralell Spheares, who dwell iust vnder either of the Poles,
whose Horizon is parallell to the Æquator, but cuts all the
Meridians at right Angles: and the latter is sometime called a
Paralell Spheare.
- They dwell (in Sphæra obliqua) in a crooked Spheare, who
inhabite any place betweene the Æquinoctiall and the Pole, whose
Horizon cuts the Æquator, the Paralells, and the Meridians at
oblique or vnequall angles.
- The third distinction is by the shadowes, which bodies doe cast
vpon the earth, iust at nooneday; for these doe not alwaies fall
one way but diuersly according to their divers scituation vpon
the Earth. Now in respect of the shadowes of mens bodies, the
inhabitants of the earth are divided into the
- The fourth distinction is by the scituation of the Inhabitants
of the Earth, compared on with another: who are called either.
- The fifth distinction is of the Length and Breadth of the Earth
and places vpon it: these may bee considered two wayes
- The Longitude must bee reckoned by the degrees of the Æquator,
the Latitude by the degrees of the Meridian.
- For example, in these two Hæmisphæres, the longitude of the whole
earth is from (C) to (A) and (B) in the Æquator. The
latitud is from (N) to (S), and from (Q) to (P) the North
and South poles, and this reckoned in any meridian. The first
meridian is (ANBS) which goes by the Canary Ilands, the
Æquinoctiall is (ABCA). Now I haue a Citty giuen so. (D) I
would know in what longitude and latitude it is. For the
longitude I consider what meridian passeth through it, which is
the meridian (NDS) which crosseth the Æquinoctiall in (I) at
15 degrees, wherefore I say that (D) stands Eastward from the
first Meridian 15 degrees. So I finde that the Citty (E) is 150
degrees Eastward, (G) 195, and (F) 345.
- For the Latitude I consider what paralell runnes through (DEG)
or (F) and I finde the 30 to passe by (D) 45 by (E) the 15
by (F) the 45 Southward by (G) and those numbers are the
latitude of the place that are distant from the Æquator, (CAB).
- Concerning the means whereby the longitude of places is found
out, there is scarce any thing that hath troubled Mathematicians
so much as the observation of it. For because no standing marke
can be taken (the Heavens alwaies running about) it must needs
bee difficult. To measure vpon the earth, going alwaies vnder the
same paralell, is a way certain in regard of some few places, but
so troublesome in it selfe, and vnprofitable in regard of other
places that ly out of that paralell, that it may be accounted a
fruitlesse labour. The voyages & accounts of Marriners at Sea,
are so full of casualty & vncertainty by reason of the doubtfull
variation of the compasse, the vnequall violence of windes and
tides, the false making of their sea cards, by which they saile,
and the ignorance of the Masters for the greatest part, as there
can hardly be any assured reckoning made by them. The best means
of observation is by Eclipses of the Sunne & Moone, which in
severall Countries are sooner or later seene, according as one
place lies farther East or farther West from another. But this
also falls out so seldome, and when it happens, is so seldome
obserued, and when it is observed, hath so many difficulties in
the precise and exact observation of it; that wee may Well
account this inquiry after the longitude of places, to be one of
those things whereof wee must be content to be ignorant, & rather
to gesse at it in Grosse, then in vaine to striue for exactnesse,
which is the cause why the tables of the longitude and latitude
of Citties, though they many times agree in the latitude, doe yet
for the most part very much differ in the Longitude.
- [Sidenote: Those
that dwell vnder the Pole haue not past 3, or
4 moneths profound as tenebras darke night, for when the Sun is
in Libra & Pisces being then nigh, the Horizon it sends forth to
them a glimmering light not vnlike to the twilight or dawning of
the day in a morning a little before the Suns rising Munster
lib. I. cap.]
The sixth Distinction is by the Length or shortnesse of the Day
in Summer time in seuerall Quarters of the earth. And this
diuision is by Climates
(χλιματα)
which are seuerall
spaces of the earth contained betweene two Paralells, in the
which the longest day in Summer excedes that in another Paralell
by halfe an Houre. There is a greate deale of Confusion and
difference betweene the late and ancient Geographers about the
distinction and diuers reckonings of the Climats. It is not
worth the labour to recount theire opinions and Calculations:
thus much is plaine, and easie to bee knowne. There are 24.
Climats in which the Day encreaseth by halfe houres from 12.
houres to 24. There are likewise 6. Climats in which the day
encreaseth by moneths, from one moneth to sixe that is halfe a
yeare. Vnder the Aequator the day is alwayes twelue houres longe,
but as you goe from it towards the Pole, the Day lengthens still
till it comes to a day halfe a yeare long. Now in what degrees
of latitude euery on of these Climats beginne and end, shall
appeare by this table following. - The seaventh and last distinction of the earth is taken from
the scituation of it in respect of the Heavens, and especially
the Sunnes motion. In regard whereof Some parts or inhabitants of
the Earth are said to be or dwell in a Right Spheare, some in a
paralell Spheare, and others in an oblique or crooked Spheare.
