In Greek mythology, Cleomestra was a Trojan princess as daughter of King Tros and probably, Callirrhoe, daughter of the river god Scamander,[1][2] or Acallaris, daughter of Eumedes.[3] She was the sister of Ilus, Assaracus, Ganymede and possibly, Cleopatra.[4] Cleomestra became the mother of Assaracus, Antenor[5] and maybe of Alcathous[6] by Aesyetes. Cleomestra and Cleopatra, as daughters of Tros are probably the same person.
