Cauac Sky of Quirigua raised Stela F to commemorate the half-period 188.8.131.52.0 1 Ahau 3 Zip. To highlight the cosmological significance of the half-cycle's ending day, Cauac Sky chose to recall the important events of other 1 Ahau cycle endings in past creations, which are inscribed in the monument's east side text. The east inscription is patterned much like that of Stela J's west text: it deals with a sequence of mythical dates that are all named 1 Ahau. The mythology of the Stela F inscription is closely related to that of Step VII from Structure 33 at Yaxchilan.

The west side inscriptions records the inauguration date of Cauac Sky's rule and includes a clause recording the capture of 18 Rabbit, ruler of Copan. The 1 Ahau dates link mythological sacrifices with Cauac Sky's historical sacrifice of 18-Rabbit, and are the basis of Cauac Sky's claim, which he continued to make to the end of his long life, that he therefore was the legitimate fourteenth successor in the Dynasty of Yax Kuk' Mo' of Copan.
NOTE: The "decapitation glyph" used in this passage describing mythological sacrifices is the same glyph used in passages describing the sacrifice of 18-Rabbit. It is the second from the left in the middle row of the photo. The diagonal element in the top half of the glyph represents a stone axe.
