Greek myths and religious practices were primarily passed down through oral storytelling before 800 BCE. These stories and practices were conveyed through generations by bards, poets, and other individuals who memorized and recited them. While some carvings in temple walls and other artistic depictions may have represented mythological scenes, they were not the primary means of transmission. Holy texts, such as the Homeric Epics (Iliad and Odyssey) and Hesiod's Theogony, were written down later and served as written sources of Greek mythology, but they were not widely available or known before 800 BCE.
