Of the many birds, one found here and on Plate 2, is a direct reference to the Maya Hunahpu and the loss of his arm to Vucub Caquix. This may indicate that Vucub Caquix who only ate yellow fruit must have originally been a bird form. The picture also shows a yellow ball attached to a star form within the mountain where the bird stands holding the arm in his beak. A "capture flag" is to the right and behind his tail.
and is part of a story involving an astronomer in a cave, an axe in the earth, and a personage with what appears to be two hands on his head, holding a fire-torch with another. The Dresden Codex has at least two long jewel-beaked birds.
Even though the stories here are unknown, there is enough information in the Madrid to tie this strange bird with the twins Hunahpu and Ixbalamque. It was Hunahpu who took his blow gun and shot the jewel out of the beak of the bird.
The word "mastelejos" is an old Spanish word which describes the mast and the spar of a ship, which is an excellent verbal description of the constellation, the Northern Cross. This constellation is part of a long-beaked bird constellation called Cygnus and in the long beak of this "bird" is a star called X-1 which was said to have exploded many, many eons ago. The question that remains is: If it was eons ago, why is its explosive flare-up so well remembered?
