4. A Macedonian officer in Alexander's army, son of Andromenes. (Diod. 17.45; Curt. 5.1.40; Arrian, iii. p. 72f., ed. Steph.) After the battle of the Granicus, B. C. 334, when the garrison of Sardis was quietly surrendered to Alexander, Amyntas was the officer sent forward to receive it from the commander, Mithrenes. (Arr. i. p. 17c. Freinsh. Sup. in Curt. 2.6.12.) Two years after, 332, we again hear of him as being sent into Macedonia to collect levies, while Alexander after the siege of Gaza advanced to Egypt; and he returned with them in the ensuing year, when the king was in possession of Susa. (Arr. iii. p. 64c.; Curt. 4.6.30, 5.1.40, 7.1.38.)

After the execution of Philotas on a charge of treason, B. C. 330, Amyntas and two other sons of Andromenes (Attalus and Simmias) were arrested on suspicion of having been engaged in the plot. The suspicion was strengthened by their known intimacy with Philotas, and by the fact that their brother Polerno had fled from the camp when the latter was apprehended (Arr. iii. pp. 72, f., 73, a.), or according to Curtius (7.1.10), when he was given up to the torture. Amyntas defended himself and his brothers ably (Curt. 7.1.18, &c.), and their innocence being further established by Polemo's re-appearance (Curt. 7.2.1, &c.; Arr. iii. p. 73a.), they were acquitted. Some little time after, Amyntas was killed by an arrow at the siege of a village. (Arr. iii. l.c.) It is doubtful whether the son of Andromenes is the Amyntas mentioned by Curtius (3.9.7) as commander of a portion of the Macedonian troops at the battle of Issus, B. C. 333; or again, the person spoken of as leading a brigade at the forcing of the "Persian Gates," B. C. 331. (Curt. 5.4.20.) But " Amyntas" appears to have been a common name among the Macedonians. (See Curt. 4.13.28, 5.2.5, 8.2.14, 16, 6.7.15, 6.9.28.)
