Note 418 — Chapter II
W. (William) Falconer translation
By the achronical rising of the Pleiades is meant the rising of this constellation, or its first becoming visible, after sunset. Vincent (Voyage of Nearchus) fixes on the 23rd October, 327 B. C., as the date of the departure of Alexander from Nicæa; August, 326 B. C., as the date of his arrival at Pattala; and the 2nd of October, 326 B. C., as the date of the departure of the fleet from the Indus.
