1 He is also called Demetrios Philometor Euergetes and Demetrios Philometor Euergetes Kallinikos on some silver and bronze coins minted in Antioch and in Seleucia Pieria. See Houghton, CSE, 390, 391 and 414; Newell, SMA, 434; SNG Spaer 2824.

2 Greek: Τρυφαινα. Bennett, Egyptian Royal Genealogy: Tryphaena, notes that she is “usually called Cleopatra Tryphaena in modern sources, although there is no ancient justification for this”.

3 Tryphaina was certainly the mother of Antiochos XI and Philip I and presumably the mother of Seleukos VI, Demetrios III, Antiochos XII and Laodike Thea. It is possible that Antiochos VIII had a second wife in the near-decade between the death of Tryphaina and his marriage to Kleopatra Selene in 103/2 BC but there is no evidence for it. (Bennett, Egyptian Royal Genealogy: Tryphaena, Cleopatra Selene)
