Autodicus was the third born of four sons to Agathocles[3] and his wife, perhaps named Arsinoe.
His paternal grandfather may have been called Alcimachus and one of his brothers was Lysimachus one of the Diadochi of Alexander the Great.
[4] His father was a nobleman of high rank who was an intimate friend of King Philip II of Macedon, who shared in Philip II’s councils and became a favorite in the Argead court.
[7] Autodicus was appointed in 321 BC[8] as one of the four Somatophylakes at Triparadeisus for the Greek Macedonian King Philip III Arrhidaeus[9] who reigned 323 BC-317 BC, who was a paternal half-brother of Alexander the Great.
[11] According to an inscription found, Autodicus had a wife called Adeia,[12] by whom he had children.
