What caused Hephaestus to be disfigured?

Hephaestus, the Greek god of fire and craftsmanship, was disfigured due to being thrown from Mount Olympus by his mother, Hera, or, in some versions, by Zeus. This act was a result of his perceived weakness or deformity, as he was born with a physical disability. The fall left him with a limp and a misshapen body, which contrasted with his exceptional skills in metalworking and craftsmanship. Despite his disfigurement, Hephaestus was revered for his talents and creativity.
