Melanthus was among the descendants of Neleus (the Neleidae) expelled from Messenia, by the descendants of Heracles, as part of the legendary "Return of the Heracleidae", later associated with the supposed "Dorian invasion".
Melanthus fled to Athens, along with other of the expelled Neleidae, Alcmaeon and the sons of Paeon. Melanthus later became a king of Athens, the successor of Thymoetes, succeeded by Codrus. Codrus was considered to be a forefather to the Greek philosopher Plato. According to Diogenes Laertius who cited Thrasylus as his source, Codrus and Melanthus also trace their descent from Poseidon.
