In 157/6 BC, he was honoured at Delphi for his diplomatic intervention with King Ptolemy VI on behalf of the city.
[1] Probably immediately after the coronation of Ptolemy VIII in 145 BC, Seleucus was appointed governor (strategos) of Cyprus and ex officio High Priest of the island.
[2] By 141/0 BC at the latest, Seleucus had acquired the rank of admiral (nauarchos) in the Ptolemaic navy – as stated by at least three inscriptions.
[3] He retained the governorship and the admiralty until around 130 BC when he must have died at an advanced age.
Seleucus was married to Artemo I, daughter of Theodorus, who had the priestly role of 'basket-bearer' (kanephoros) of the deified Arsinoe II in Alexandria in 177/6 BC.
