[505] “Vasa horoscopica.” “Vasa horoscopica appellat horologia in plano descripta, horizonti ad libellam respondentia. Vasa dicuntur, quod area in qua lineæ ducebantur, labri interdum instar et conchæ erat, cujus in margine describebantur horæ. Horoscopa, ab ὥρα et σκοπέω, hoc est, ab inspiciendis horis.” Hardouin, in Lemaire, i. 391.
[506] These distances are respectively about 38 and 62 miles.
[507] We are not to expect any great accuracy in these estimates, and we accordingly find, that our author, when referring to the subject in his 6th book, ch. 39, makes the shadow at Ancona 1⁄35 greater than the gnomon, while, in Venetia, which is more northerly, he says, as in the present chapter, that the shadow and the gnomon are equal in length. See the remarks of M. Alexandre in Lemaire, ut supra.
[508] This would be about 625 miles. Strabo, ii. 114, and Lucan, ii. 587, give the same distance, which is probably nearly correct. Syene is, however, a little to the north of the tropic.
[509] This remark is not correct, as no part of this river is between the tropics. For an account of Onesicritus see Lemaire, i. 203, 204.
[510] “In meridiem umbras jaci.” M. Ajasson translates this passage, “les ombres tombent pendant quatre-vingt-dix jours sur le point central du méridien.” ii. 165. But I conceive that Holland’s version is more correct, “for 90 days’ space all the shadows are cast into the south.” i. 36. The remarks of M. Alexandre are to the same effect; “... ut bis solem in zenitho haberet (Ptolemais), Maii mensis et Augusti initio; interea vero, solem e septemtrione haberet.” Lemaire, i. 393.
[511] About 625 miles.
[512] These days correspond to the 8th of May and the 4th of August respectively.
[513] There is considerable uncertainty respecting the identity of this mountain; our author refers to it in a subsequent part of his work, where it is said to be in the country of the Monedes and Suari; vi. 22. See the note of Alexandre in Lemaire, i. 394.
[514] Our author, in a subsequent part of his work, vi. 23, describes the island of Patale as situated near the mouth of the Indus; he again refers to it, xii. 25. His account of the position of the sun does not, however, apply to this place.
