Darius, the Persian, had a battle with Alexander
near the River Granicus, where he lost seven satraps, and
five hundred and two chariots armed with scythes. And yet
he would have tried the fortune of another battle the day
following; but his son Ariobarzanes, in favor of Alexander, undertook to betray his father into his hands. The
father was so transported with passion at the indignity of
the thing, that he cut off his son's head for it.—Arelades
Cnidius, in the Third of his Macedonian History.
Brutus, that was created consul by the unanimous vote
of the citizens, forced away Tarquinius Superbus into
banishment for his abominable tyranny. He fled to the
Tuscans, and by their assistance made war upon the
Romans. The sons were treating to betray the father;
the business was discovered, and they lost their heads for
it.—Aristides Milesius, in his Italian History.
