[531] The astronomical cubit of the ancients equalled 2 degrees. It therefore follows that in the regions alluded to by Hipparchus, the sun at the winter solstice rose no higher than 18 degrees above the horizon. This would give a latitude of a little above 48 degrees. We afterwards find that Hipparchus placed the mouth of the Dnieper, and that part of France here alluded to, under 48° 29′ 19″, and we know that at this latitude, which is only 20′ 56″ different from that of Paris, there is no real night during the longest days of the summer.

[533] Lit., during the winter days, but the winter solstice is evidently intended.
[534] Read about 10,500. This correction is borne out by the astronomical indications added by Hipparchus.
[535] Strabo supposed the latitude of Ireland to be 52° 25′ 42″. Countries north of this he considered to be altogether uninhabitable on account of their inclemency.
[536] Equinoctial hours.
[537] Read 10,500, as above.
