Returning from these ideas of later development to the primitive source of their suggestion, let us now examine the native picture of Xonecuilli, Ursa Minor, preserved in the unpublished Academia MS. of Sahagun’s Historia, in Madrid (fig. 16, no. 1). It is an exact representation of the star-group. The fact that the seven stars are figured of the same size in accurate relation to each other, either proves that the eyesight of the native astronomers was extremely keen and their atmosphere remarkably clear, or that possibly, the minor stars of the group were more brilliant in ancient times, than they are now. Astronomers tell us, for instance, that as late as the seventeenth century the star in the body of Ursa Major nearest to the tail, was as bright as the others, while it is now of the fourth magnitude only. It must be admitted that the shape of the constellation resembles an S. An SS sign is mentioned by Sahagun (Historia, book VIII, chap. 8) as occurring frequently, as a symbolical design on native textile fabrics. It figures as such, in the black garments of the female consort of Mictlantecuhtli in the Vienna Codex, pp. 23 and 33. He denounces it as suspect and hints that it was intimately connected with the ancient religion. S-shaped sacred cakes, called Xonecuilli, were made during the feast of Macuilxochitl=five flowers, and are figured (fig. 16, no. 2) in the B. N. MS. (p. 69) with a four-cornered cross-shaped cake of a peculiar form (fig. 20, III), which is found associated with five dots or circles in the Codices and also with the Tecpatl-symbol of the North (fig. 20, I and II).
