Tisander

In Greek mythology, Tisander was according to some sources a son of Jason and Medea. He and his brother Alcimenes were murdered in Medea's revenge plot against Jason, after he had abandoned her and gone to marry Glauce, the daughter of King Creon of Corinth.

Sources differ over the number and names of Medea's children, varying between one son, Argos, and fourteen (seven daughters and seven sons):

Her children are, according to some accounts, Mermerus, Pheres or Thessalus, Alcimenes and Tisander, and, according to others, she had seven sons and seven daughters, while others mention only two children, Medus (some call him Polyxemus) and Eriopis, or one son Argos.
