In Greek mythology, Mentor (Greek: Μέντωρ / Méntōr; gen.:
Μέντορος) was the son of Alcumus and, in his old age, a
friend of Odysseus. When Odysseus left for the Trojan War he
placed Mentor in charge of his son, Telemachus, and of his
palace. When Athena visited Telemachus she took the disguise
of Mentor to hide herself from the suitors of Telemachus'
mother Penelope. As Mentor, the goddess encourages
Telemachus to stand up against the suitors and go abroad to
find out what happened to his father.

Mentor) takes the form of a swallow and the suitors' arrows
have no effect on him...
