Pausanias Description of Greece 2.16.2

[2] Then there was Abas the son of Lynkeus, and his own sons Akrisios and Proitos divided the kingship [ basileiā] between themselves. Akrisios remained where he was at Argos, and Proitos took over the Hēraion, Mideiā, Tiryns, and the Argive coastal region. Traces [ sēmeia] of the residence [ oikēsis] of Proitos in Tiryns remain to the present day. Afterwards Akrisios, learning that Perseus himself was not only alive but accomplishing [ apodeiknusthai] great deeds, withdrew to Larisa, by [the river] Pēneios. And Perseus, wishing at all costs to see the father of his mother and to greet him with fair words and deeds, visited him at Larisa. Being in the prime of life and proud of being the inventor of the discus, he showed off [ apodeiknusthai] [his skill in throwing the discus] in front of everybody, and Akrisios, through the agency of some superhuman force [ daimōn], stepped unnoticed into the path of the discus.
