According to legend, Cusco (Qosqo in Quechua, or "earth's navel") is the place where the golden rod finally sunk into the ground, and where Manco Capac founded his capitol city of the Inca Empire, in the 12th century. In the early 1400s the ninth Inca, Pachucutec, began the expanding the Inca tribe. Pachucutec was a great urban developer, as well as politician. He designed Cusco in the shape of a Puma, whose head and teeth are formed by the fortress of Saqsayhuaman. He is also responsible for the building of Qorikancha, (garden of gold), the most important structure in the entire empire. Qorikancha was covered with plates of gold, and its interior contained a series of temples dedicated to the sun, moon, rainbow, stars, and thunder and lightning. Golden, bejeweled objects were found throughout, and the Temple of the Moon was covered in sheets of silver. The courtyard, or "golden garden" contained life-size gold replicas of the animals and plants of the kingdom.
