How does argos die?

In Greek mythology, Argos, a giant with a hundred eyes, was tasked with guarding Io, a priestess of Hera. He was eventually killed by Hermes, who was sent by Zeus to rescue Io. Hermes lulled Argos to sleep with music and stories before killing him, and after his death, Hera honored Argos by placing his eyes on the peacock's feathers.
