The Eagle, the Snake, and the Cactus in the Founding of Tenochtitlan - This illustration depicts the founding of Tenochtitlan (present-day Mexico City). An eagle is shown devouring a bird while perched on a flowering cactus. The cactus grows from a rock in the middle of a lake. Footsteps of the Mexicans are shown approaching the base of the cactus. On the right is Tenoch (known from his glyph of a flowering cactus), who led the Aztecs to Tenochtitlan. On the left is Tochtzin, or Mexitzin (known from his glyph of a rabbit), who came from Calpan (known from the glyph of a house with a flag), Tenoch's co-ruler. The two rulers sit on basketwork thrones. At upper right is the symbol of Copil, son of Malinalxochitl, or five dots with crossed arrows, on a shield.
