According to a creation myth recorded by 16th century Spanish chronicler Juan Diez de Betanzos, the Inca's supreme-creator god Con Tici Viracocha rose from Lake Titicaca "during the time of darkness to bring forth light." Most often described as an old man with fair-skin and a beard, wearing a long robe and carrying a staff and a book, after crafting the sun, moon, planets and stars from islands on Lake Titicaca he created "a race of brainless giants from stone," which he destroyed with a great flood. Viracocha then used clay and successfully forged the first man, Manco Capac (meaning: splendid foundation) the son of Inti the sun god, and his sister Mama Uqllu, which means "mother fertility".
