About Sisines, of Comana
Archelaus was a Cappadocian Greek nobleman, possibly of Macedonian descent. He was the son and namesake of the Roman Client Ruler and High Priest of Comana, Cappadocia, Archelaus  by an unnamed Greek woman. He also had an unnamed sister and his paternal uncle was the Pontic soldier Diogenes, who served in the army of King Mithridates VI of Pontus. His paternal grandfather also called Archelaus, the Pontic General who participated in the Mithridatic Wars. His paternal grandmother may have been a Pontic Princess one of the daughters born from the concubine of Mithridates VI as his father had descended from Mithridates VI.
In January/February 55 BC after the deaths of his father and sister, Archelaus succeeded his father as High Priest Temple Ruler of the Comana Cappadocia. Archelaus was the High Priest of the Roman Goddess of War, Bellona. When Marcus Tullius Cicero served as Proconsul of Cilicia in 51 BC, Archelaus assisted with troops and money for those who created disturbances in Cappadocia and threatened then King Ariobarzanes III of Cappadocia. Cicero compelled Archelaus to quit the campaign against Ariobarzanes III.
In 47 BC the Roman Dictator Gaius Julius Caesar after the conclusion of his military victory against the Triumvir Pompey, deprived and deposed Archelaus of his office of high priest and rule over Comana. Archelaus was replaced by another Greek nobleman called Lycomedes. Pompey was their family patron  and it was he that appointed his father as High Priest Ruler of the temple state of Comana. The fate of Archelaus afterwards is unknown.
Archelaus had married a Cappadocian Greek Hetaera called Glaphya. Glaphyra bore Archelaus two sons: Archelaus Sisines, also known as King Archelaus of Cappadocia who reign from 36 BC until his death in 17  Sisines
