Alexander's Ancestors

Like all ancient kings, Alexander claimed that the gods were his ancestors. Already in the fifth century, the Macedonian kings said that they descended from Perdiccas, who descended from Temenos, a king of Argos; and he was great-grandchild of Hyllus, the son of Heracles. The oldest source for this family tree can be found in book eight of the Histories of the Greek researcher Herodotus of Halicarnassus (text).
