Note 125 — Chapter XCII · ASIATIC CAMPAIGNS OF ALEXANDER.
Reading edition
Harpokration and Photius, v. Πεζέταιροι, Demosth. Olynth. ii. p. 23; Arrian, iv. 23, 1. τῶν πεζεταίρων καλουμένων τὰς Τάξεις, and ii. 23, 2, etc.
Since we know from Demosthenes that the pezetæri date from the time of Philip, it is probable that the passage of Anaximenes (as cited by Harpokration and Photius) which refers them to Alexander, has ascribed to the son what really belongs to the father. The term ἑταῖροι, in reference to the kings of Macedonia, first appears in Plutarch, Pelopidas, 27, in reference to Ptolemy, before the time of Philip; see Otto Abel, Makedonien vor König Philip, p. 129 (the passage of Ælian referred to by him seems of little moment). The term Companions or Comrades had under Philip a meaning purely military, designating foreigners as well as Macedonians serving in his army: see Theopompus, Frag. 249. The term, originally applied only to a select few, was by degrees extended to the corps generally.
