The Chronicle concerning Alexander the Great ("Alexander Chronicle"; ABC 8; BCHP 1) is one of the Mesopotamian chronicles written in ancient Babylonia in the Hellenistic Period. It is very hard to understand but clearly mentions several events from the reign of Alexander the Great.
The Babylonian Alexander Chronicle (BCHP 1; a.k.a. ABC 8, Chronicle 8) is one of the Mesopotamian chronicles written in ancient Babylonia in the Hellenistic Period. It deals with events from the reigns of the Persian king Darius III Codomannus and his Macedonian successor Alexander the Great.
The cuneiform tablet (BM 36304) is in the British Museum and was first published by A.K. Grayson in 1975 in a book called Assyrian and Babylonian Chronicles. On this website, a new reading is proposed by Bert van der Spek of the Free University of Amsterdam (Netherlands). The official publication can be found in Achaemenid History XIII (2003).
An alternative reading, not by Van der Spek but published in Lendering (2004), is proposed here.
In Van der Spek's reconstruction, the horizontal lines in this tablet are interpreted as indications of years. However, as Van der Spek indicates (here), on several tablets the lines indicate months. The following text shows what happens when we read the obverse of the Alexander Chronicle in this fashion. The weakness of this reconstruction is line 8, where two months are dealt with in one line. This may have happened in line 10 too. It can not be excluded that the events now mentioned in months VIII and IX in fact belong to IX and X.
