Aristobulus of Chalcis

Aristobulus of Chalcis (Greek: Ἀριστόβουλος) was a son of Herod of Chalcis and his first wife Mariamne. Herod of Chalcis, ruler of Chalcis in Iturea, was a grandson of Herod the Great through his father, Aristobulus IV. Mariamne was a granddaughter of Herod the Great through her mother, Olympias; hence Aristobulus was a great-grandson of Herod the Great on both sides of his family.

Aristobulus was married to Salome after the death of her first husband, Philip the Tetrarch. With her Aristobulus had three sons: Herod, Agrippa, and Aristobulus Three coins with portraits of him and Salome have been found.

Aristobulus did not directly succeed his father as ruler of the Chalcis. Rather, upon his father's death in 48 AD, the emperor Claudius gave the realm to Aristobulus' first cousin, Herod Agrippa II. When in 52 AD Agrippa was given the territories previously governed by Philip the Tetrarch (also known as Herod Philip II) and Lysanias, Aristobulus was subsequently given Chalcis. He reigned as Aristobulus of Chalcus until his death in 92 AD, when Chalcis became part of Roman Syria.

He has been identified with the Aristobulus appointed by Nero as King of Armenia Minor in 55 AD, who participated with his forces in the Roman-Parthian War of 58–63, receiving a small portion of Gerater Armenia in exchange. This Aristobulus was displaced from Armenia Minor in 72 AD, but is thought to be the "Aristobulus of Chalcidice" who supported Lucius Caesennius Paetus, proconsul of Syria, in the war against Antiochus of Commagene in 73 AD, and was in consequence compensated with a new kingdom, "probably Chalcis ad Belum" (modern Qinnasrin, in northern Syria. Assuming all these Aristobuli were indeed the same person, he would seem to have been ruler, at various times, of the Iturean Chalcis, Armenia Minor, and Chalcis ad Belum.
