(Ἵπποκλος; Híppoklos). H., (probably the first) tyrant of Lampsacus, was supported by the Persians and took part in the Scythian campaign of Darius  I c. 513 BC (Hdt. 4,138). Hippias  of Athens concluded a marriage alliance with him through the marriage of his daughter Archedice with H.' son and successor Aeantides, which at the same time meant a move in the direction of the Persians (Thuc. 6,59) and possibly was a reason for Sparta's intervention in Athens in 511/510 BC [1. 301].
