Antigonus, Son of John Hyrcanus (Ἀντίγονος, Antigonos; alternate spelling Antigonos). A Hasmonean ruler.

Josephus notes that after the death of the high priest John Hyrcanus I, Hyrcanus’ son Aristobulus I crowned himself king. Aristobulus elevated his brother Antigonus to equal rank, while placing other members of his family, including his own mother, in prison. According to Josephus, Aristobulus had an unusually cruel nature, which came to the forefront in his dealings with his mother. He intended to starve her in prison. Although Aristobulus’ dealings with his mother were a point of disagreement between Aristobulus and Antigonus, the king nevertheless continued to extend kindness to Antigonus.

During the Feast of Tabernacles, Aristobulus became ill, and Antigonus went to celebrate the festival with his soldiers. Some of his men led others to start the rumor that Antigonus was coming to take Aristobulus’ life. Aristobulus sent word to Antigonus to come unarmed, but the queen plotted against Antigonus by sending a contrary message to the king, further convincing him that Antigonus intended to take the kingdom by force. As a result, Aristobulus’ men killed Antigonus at Strato’s Tower (Josephus, Antiquities 13.301–17).
