He was king of Argos, whence that city is called Abas.
His story is that when the Danaides, by the desire of their father, killed their husbands in one night, Hypermnestra alone spared the life of her husband Lynceus.
The cause of Hypermnestra sparing Lynceus is not the same in all accounts. It is also said that she assisted her husband in his escape from the vengeance of Danaus, that he fled to Lyrceia (Lynceia), and from thence gave a sign with a torch that he had safely arrived there.
Hypermnestra returned the sign from the citadel of Argos, and in commemoration of this event the Argives celebrated every year a festival with torches.
When Lynceus received the news of the death of Danaus from his son Abas, Lynceus gave to Abas the shield of Danaus, which had been dedicated in the temple of Hera, and instituted games in honour of Hera, in which the victor received a shield as his prize.
According to some, Lynceus slew Danaus and all the sisters of Hypermnestra in revenge for his brothers. Lynceus and his wife were revered at Argos as heroes, and had a common sanctuary, and their tomb was shown there not far from the altar of Zeus Phyxius.
Their statues stood in the temple at Delphi, as a present from the Argives.
