The last members of the once mighty Seleucid dynasty are shadowy figures; local dynasts with complicated family ties whose identities are hard to ascertain: many of them also bore the same names.
Some time after Tigranes had conquered Syria (83 BC), his mother travelled to Rome to have her sons recognized as kings of Egypt, but to no avail.
In 2002, the numismatist Brian Kritt announced the discovery and decipherment of a coin bearing the portrait of Cleopatra Selene and a co-ruler.
Kritt read the name of the ruler as Seleucus Philometor and, based on the epithet, identified him with Cleopatra Selene's son, unnamed by Cicero.
Kritt gave the newly discovered ruler the regnal name Seleucus VII, and considered it very likely that he is identical with Kybiosaktes.
