[38] The date here fixed by Arrian is the 2nd of October 326 B.C., but the computation now generally accepted refers the event to the year after to suit the chronology of Alexander’s subsequent history (see Clinton’s F. Hell. II. pp. 174 and 563, 3rd ed.). There was an Archon called Kephisidoros in office in the year B.C. 323-322; so Arrian has here either made a mistake, or perhaps an Archon of the year 326-325 may have died during his tenure of office, and a substitute called Kephisidôros been elected to fill the vacancy. The _lacuna_ marked by the asterisks has been supplied by inserting the name of the Makedonian month Dius. The Ephesians adopted the names of the months used by the Makedonians, and so began their year with the month Dius, the first day of which corresponds to the 24th of September. The 20th day of Boedromion of the year B.C. 325 corresponded to the 21st of September.
[39] Regarding the sunken reef encountered by the fleet after leaving Koreatis, Sir Alexander Burnes says: “Near the mouth of the river we passed a rock stretching across the stream, which is particularly mentioned by Nearchus, who calls it _a dangerous rock_, and is the more remarkable since there is not even a stone below Tatta in any other part of the Indus.” The rock, he adds, is at a distance of six miles up the Pitti. “It is vain,” says Captain Wood in the narrative of his _Journey to the Source of the Oxus_, “in the delta of such a river (as the Indus), to identify existing localities with descriptions handed down to us by the historians of Alexander the Great ... (but) Burnes has, I think, shown that the mouth by which the Grecian fleet left the Indus was the modern +Piti+. The ‘dangerous rock’ of Nearchus completely identifies the spot, and as it is still in existence, without any other within a circle of many miles, we can wish for no stronger evidence.” With regard to the canal dug through this rock, Burnes remarks: “The Greek admiral only availed himself of the experience of the people, for it is yet customary among the natives of Sind to dig shallow canals, and leave the tides or river to deepen them; and a distance of five stadia, or half a mile, would call for not great labour. It is not to be supposed that sandbanks will continue unaltered for centuries, but I may observe that there was a large bank contiguous to the island, between it and which a passage like that of Nearchus might have been dug with the greatest advantage.” The same author thus describes the mouth of the Piti:—“Beginning from the westward we have the Pitti mouth, an embouchure of the Buggaur, that falls into what may be called the Bay of Karachi. It has no bar, but a large sandbank, together with an island outside prevent a direct passage into it from the sea, and narrow the channel to about half a mile at its mouth.”
