Presbon was one of four (or five) sons of Phrixus and Chalciope. He was also a grandson of King Aeëtes of Colchis.
Presbon and his brothers were raised in Colchis, but after their father died, he and his brothers set out to avenge their father's ill treatment in the hands of king Athamas of Orchomenus and were stranded on the Island of Ares the War God in the Black Sea until they were rescued from the island by the Jason and the Argonauts. Once Jason received discovered that Phrontis and his brothers were grandsons of King Aeëtes of Colchis, Jason convinced Phrontis and his brothers to return with him to Colchis and help him to obtain the Golden Fleece. Jason also questioned Phrontis and his brothers on the layout and security of the land. After the Fleece was retrieved from Colchis, Phrontis and his brothers returned with the Argo's crew to Greece. His brothers were Kytissorus, Phrontis, Argus and Melas.
