And when he [Perseus] comes he doesn’t find Akrisios in Argos because he was afraid of him and retreated to the Pelasgians at Larissa. And since he didn’t catch him, he leaves Danae with her mother Eurydike, and Andromeda and the Kyklopes, but he himself went to Larissa. And when he arrives, he recognizes Akrisios and convinces him to follow with him to Argos. And just when they were about to leave, he happens on a contest of young men at Larissa; and Perseus enters the contest, and takes the discus and throws it; and it wasn’t a pentathlon, but they were contesting each particular one of the contests. And the discus rolls into Akrisios’s foot and wounds him. And Akrisios, getting sick from this, dies there at Larissa, and Perseus and the Larissans bury him in front of the city, and the locals make a hero temple there. And Perseus goes back away from Argos (translation by Silvio Curtis).
Perseus hastened with Danae and Andromeda to Argos in order that he might behold Acrisius. But he, learning of this and dreading the oracle, forsook Argos and departed to the Pelasgian land. Now Teutamides, king of Larissa, was holding athletic games in honor of his dead father, and Perseus came to compete. He engaged in the pentathlum, but in throwing the quoit he struck Acrisius on the foot and killed him instantly (original Greek).

When Acrisius was detained there [on Seriphus] by a storm, Polydectes died, and at his funeral games the wind blew a discus from Perseus’ hand at Acrisius’ head which killed him (original Latin).
After such deeds, victorious Perseus turned,
and sought the confines of his native land;
together with his bride; which, having reached,
he punished Proetus—who by force of arms
had routed his own brother from the throne
of Argos. By his aid Acrisius,
although his undeserving parent, gained
his citadels once more: for Proetus failed,
with all his arms and towers unjustly held,
to quell the grim-eyed monster, snake-begin (original Latin).
Megapenthes, son of Proetus, killed Perseus, son of Jove and Danae on account of the death of his father (original Latin).
