Perseus
Περσεύς
The hero who beheaded a monster by watching only its reflection in his shield.
Since looking at Medusa directly turned you to stone, he cut off her head watching only her reflection in the bronze shield Athena gave him.
He went armed with borrowed gear: the winged sandals of Hermes and the cap of invisibility of Hades.
On the way home he rescued Andromeda, chained to a rock, and turned a sea monster to stone with the severed head.
