Regardless of his precise ancestry, Priapatius succeeded Arsaces II in 191 BC. Like many Arsacid rulers, not much is known about Priapatius. His coinage in terms of style followed the same model as that of his predecessors. The obverse shows a beardless portrait of him wearing a soft cap (
kyrbasia), whilst the reverse shows him carrying a bow. However, changes to the titulary were made on the coinage: the
Greek title of (
Basileus) was for the first time added and made regular on his coinage, and the title (Great) was also added. The adoption of these titles were most likely associated with the Arsacid reconquest of the lands lost to the
Seleucid king
Antiochus III the Great (), who had in 210 BC made a large-scale expedition in the east, including
Hyrcania. There, he possibly compelled Arsaces II to abandon his right to mint coins freely. Afterwards, however, the fragility of the Seleucid Empire gave Arsaces II and later Priapatius the opportunity to resume having their coins minted freely. Like the rest of the Arsacid kings, Priapatius used the title of
Arsaces on his coinage, which was the name of the first Arsacid ruler
Arsaces I (), which had become a royal honorific among the Arsacid monarchs out of admiration for his achievements. Priapatius was the father of three Arsacid kings,
Phraates I (), who was his oldest son and successor,
Mithridates I (), and
Artabanus I (). == References ==
