There Phegeus offered him succor and gave him his daughter Arsinoe or Alphesiboea, who received from Alcmaeon, as a wedding present, the robe and necklace of Harmonia.
However, because of his crime, the ground became barren in Psophis and an oracle told Alcmaeon to depart to Achelous and to stand another trial on the river bank.
Alcmaeon then went to Psophis and told Phegeus that it had been predicted that he should be rid of his madness when he had brought the robe and necklace to Delphi and dedicated them.
So the sons of Phegeus, Pronous and Agenor or Temenus and Axion, following their father's orders, waited for Alcmaeon in an ambush and killed him.
[6] When Callirrhoe learned that she was a widow she requested of Zeus that the sons she had by Alcmaeon might be full-grown in order to avenge their father's murder.
