Can you give the mythological name for the mountain in Greece where no woman, female animal, child, eunuch, or person with a beardless face is allowed to set foot.

This peninsula in northeastern Greece gets its name from a figure in Greek mythology. According to legend, Athos was a Thracian giant who battled the Olympian gods. During the fight, he threw a colossal rock at the sea god Poseidon, which landed in the Aegean and became the mountain. While its origins are mythological, the mountain is renowned today as a major center of Eastern Orthodox monasticism. Often referred to as the "Holy Mountain," it is a semi-autonomous monastic state comprised of twenty monasteries and is home to approximately 2,000 monks.

The strict entry prohibitions are rooted in a rule known as the "avaton," which has been in place for over a thousand years. This rule specifically forbids access to women and most female animals. The ban was officially proclaimed in an imperial charter in 1046 to help the resident monks maintain their vows of celibacy. The prohibition also traditionally extends to children, eunuchs, and individuals without beards, as they were historically seen as potential temptations.

The spiritual justification for this exclusion is the belief that the entire peninsula is the exclusive "garden" of the Virgin Mary. According to tradition, Mary was sailing to Cyprus when a storm forced her ashore on the mountain. She was so taken by its beauty that she blessed it, and it was dedicated to her glory alone. Consequently, she is considered the only female presence welcome on Mount Athos, reinforcing the avaton and preserving the sanctity of the monastic community.
