Note 534 — Chapter LXXIX · FROM THE FOUNDATION OF MESSENE AND MEGALOPOLIS TO THE DEATH OF PELOPIDAS.
Reading edition
Diodor. xv, 67.
The transactions of Macedonia and Thessaly at this period are difficult to make out clearly. What is stated in the text comes from Diodorus; who affirms, however, farther,—that Pelopidas marched into Macedonia, and brought back as a hostage to Thebes the youthful Philip, brother of Alexander. This latter affirmation is incorrect; we know that Philip was in Macedonia, and free, after the death of Alexander. And I believe that the march of Pelopidas into Macedonia, with the bringing back of Philip as a hostage, took place in the following year 368 B.C.
Justin also states (vii, 5) erroneously, that Alexander of Macedon gave his brother Philip as a hostage, first to the Illyrians, next to the Thebans.
