After the death of Phoroneus, the two elder brothers, Pelasgus and Iasus, divided his dominions between themselves in such a manner that Pelasgus received the country about the river Erasmus, and built Larissa, and Iasus the country about Elis. After the death of these two, Agenor, the youngest, invaded their dominions, and thus became king of Argos.[8] According to Pausanias, he was the successor of his father Triopas on the throne of Argos while his brother Agenor succeeded him as the king afterwards.[9]
