Thibron's activities after the murder of Harpalus are described by Diodorus and Arrian (Succ. f 1.16–19 Roos). Both sources give considerable detail, clearly taken from a common original, but concentrate on different aspects of the story. Arrian (or rather his excerptor Photius) is more attracted by the sensational details of his defeat and capture by Ophellas, whereas Diodorus concentrates on the earlier part of the narrative. It is evident from their joint account that the campaigns in Cyrenaica were full of action and took place over a considerable period. Unfortunately they relate the story in a single piece, placed in the general context of the end of the Lamian War; there is no precise chronological fixing. Justin permits a rough dating when he places Ptolemy's acquisition of Cyrene (the ultimate result of Thibron's campaigns) some time before Perdiccas' invasion of Egypt in 321 (xiii.6.20, 8.1). The Parian Marble to some degree confirms, synchronising Ophellas' operations in Cyrene with the fall of Athens, in the archon year 322/1 (FGrH 239 b io: Ptolemy's visit in person (Arr. Succ. f 1.19) is dated to the next year, after the death of Perdiccas). The evidence so far is consistent and indicates that the war was over and Thibron dead by the end of 322 b.c.
