The back of Stela B (foreground) is occupied by a huge monster mask, meant to represent a mountain. Inside the right eye of the mask, the artist even tells us what specific mountain we are dealing with: Mo' Witz or Macaw Mountain. The monument's main text (carved on its sides and not visible here) tells us that the other face of the stela depicts the Copan king "in the guise of the Lord of Macaw Mountain" (see photo #24), for whatever ritual he was commemorated as conducting. To the left and back, we see Stela C with its turtle altar and in the far background, Stela F.
