Gate of the Sun is the most important and famous sculpture of  Tiwanaku. Worked in andesite , it has a beautiful lintel where the figure of the Viracocha stands. This figure with a head that radiates, represents the God Creator, or Inti for the Incas, is also known as the crying God because of the tears you can see on its face. Both, eyes and tears are in low relief and were filled with gold.
 The tears represent the rain, very important for life. Surrounding the  Viracoha are 48 figures called  chasquis or God Messengers. The fourth row is part of the huge calendar in the temple.
