J.E. Sandys, A History of Classical Scholarship Vol. 1:
“There are some dubious stories of early interpolations in the Homeric poems. Thus Peisistratus is said to have introduced into the Odyssey a line in honour of the Attic hero, Theseus; and both Solon and Peisistratus are credited with the insertion of a line referring to Ajax, for the supposed purpose of proving that Salamis was an ancient possession of Athens; but, as the recovery of Salamis took place in Solon’s time, while Peisistratus was still a boy, Solon alone should have been mentioned in this connexion Onomacritus, who is said to have been one of the four who put together the Homeric poems under the authority of Peisistratus, was, according to Herodotus, caught in the act of interpolating the oracles of Musaeus, and was banished by the tyrant’s son, Hipparchus.”
