And over this nou understond,
Air is the thridde of elementz,
Of whos kinde his aspirementz
Takth every lifissh creature,
The which schal upon erthe endure:
For as the fissh, if it be dreie,
Mot in defaute of water deie, 260
Riht so withouten Air on lyve
No man ne beste myhte thryve,
The which is mad of fleissh and bon;
There is outake of alle non.
This Air in Periferies thre
Divided is of such degre,
Benethe is on and on amidde,
To whiche above is set the thridde:
And upon the divisions
There ben diverse impressions 270
Of moist and ek of drye also,
Whiche of the Sonne bothe tuo
Ben drawe and haled upon hy,
And maken cloudes in the Sky,
As schewed is at mannes sihte;
Wherof be day and ek be nyhte
After the times of the yer
Among ous upon Erthe her
In sondri wise thinges falle.
The ferste Periferie of alle 280
Engendreth Myst and overmore
The dewes and the Frostes hore,
After thilke intersticion
In which thei take impression.
Fro the seconde, as bokes sein,
The moiste dropes of the reyn
Descenden into Middilerthe,
And tempreth it to sed and Erthe,
And doth to springe grass and flour.
And ofte also the grete schour 290
Out of such place it mai be take,
That it the forme schal forsake
Of reyn, and into snow be torned;
And ek it mai be so sojorned
In sondri places up alofte,
That into hail it torneth ofte.
The thridde of thair after the lawe
Thurgh such matiere as up is drawe
Of dreie thing, as it is ofte,
Among the cloudes upon lofte, 300
And is so clos, it may noght oute,—
Thanne is it chased sore aboute,
Til it to fyr and leyt be falle,
And thanne it brekth the cloudes alle,
The whiche of so gret noyse craken,
That thei the feerful thonder maken.
The thonderstrok smit er it leyte,
And yit men sen the fyr and leyte,
The thonderstrok er that men hiere:
So mai it wel be proeved hiere 310
In thing which schewed is fro feer,
A mannes yhe is there nerr
Thanne is the soun to mannes Ere.
And natheles it is gret feere
Bothe of the strok and of the fyr,
Of which is no recoverir
In place wher that thei descende,
Bot if god wolde his grace sende.
And forto speken over this,
In this partie of thair it is 320
That men fulofte sen be nyhte
The fyr in sondri forme alyhte.
Somtime the fyrdrake it semeth,
And so the lewed poeple it demeth;
Somtime it semeth as it were
A Sterre, which that glydeth there:
Bot it is nouther of the tuo,
The Philosophre telleth so,
And seith that of impressions
Thurgh diverse exalacions 330
Upon the cause and the matiere
Men sen diverse forme appiere
Of fyr, the which hath sondri name.
Assub, he seith, is thilke same,
The which in sondry place is founde,
Whanne it is falle doun to grounde,
So as the fyr it hath aneled,
Lich unto slym which is congeled.
Of exalacion I finde
Fyr kinled of the fame kinde, 340
Bot it is of an other forme;
Wherof, if that I schal conforme
The figure unto that it is,
These olde clerkes tellen this,
That it is lik a Got skippende,
And for that it is such semende,
It hatte Capra saliens.
And ek these Astronomiens
An other fyr also, be nyhte
Which scheweth him to mannes syhte, 350
Thei clepen Eges, the which brenneth
Lik to the corrant fyr that renneth
Upon a corde, as thou hast sein,
Whan it with poudre is so besein
Of Sulphre and othre thinges mo.
Ther is an other fyr also,
Which semeth to a mannes yhe
Be nyhtes time as thogh ther flyhe
A dragon brennende in the Sky,
And that is cleped proprely 360
Daaly, wherof men sein fulofte,
“Lo, wher the fyri drake alofte
Fleth up in thair!” and so thei demen.
Bot why the fyres suche semen
Of sondri formes to beholde,
The wise Philosophre tolde,
So as tofore it hath ben herd.
