Note 115 — Chapter III · 1474-1492.

“Marinus, the Tyrian, misled by the length of time occupied in the navigation from Myos Hormos to India, by the erroneously assumed direction of the major axis of the Caspian from west to east, and by the over-estimation of the length of the land route to the country of the Seres, gave the old continent a breadth of 225°, instead of 129°. The Chinese coast was thus advanced to the Sandwich Islands. Columbus naturally preferred this result to that of Ptolemy, according to which Quinsay should have been found in the meridian of the eastern part of the archipelago of the Carolinas. Ptolemy, in the Almagest (ii. 1), places the coast of Sinae at 180°, and in his Geography (lib. i. cap. 12) at 177¼°.”—Humboldt: Cosmos. Otté’s trans. vol. ii. p. 645. Note.
