According to chronicler Garcilaso de la Vega, son of an Inca princess and a Spanish knight and landowner, myth had it that the original Inca, Manco Capac, along with his sister / bride, was sent down by his father, the sun - god, to Lake Titicaca to bring all peoples under worship of the sun.
Müüdi järgi saatis esimese inka, Manco Cápaci, ning tema õest mõrsja maa peale Titicaca järve äärde nende isa, päikesejumal, et koguda kõik rahvad päikest kummardama, nagu jutustab kroonik Garcilaso de la Vega, inka printsessi ning hispaania rüütli ja maaomaniku poeg.
