One of the most beautiful vessels from the cemetery of Sikyatki is the "butterfly vase," the complicated design on which I have figured in plate LX of the Smithsonian Report for 1895. I have represented a sector of this design in figure 5 in order to point out the feather decorations which form an important element in the ornamentation. The other sectors closely resemble that figured, with the exception that the butterflies in alternating sections have different markings on their heads, indicative of the sex. The butterfly here represented is female, and it is interesting to note the fact that the symbol of the female was the same when this vase was made as that now used in Hopi ceremonials.[11] There are three clusters of feathers (_f_) in this section, and each cluster is composed of three members. One of these clusters corresponds with those from the head of the reptile, figure 2. The three feathers shown in the cut below the butterfly, and peripherally placed on the surface of the vase, are likewise feather symbols, but as they have different markings from the others are probably from a different genera of birds. This form of feather symbol is a common one on ancient Sikyatki ware. One of the best illustrations may be seen in the wing of the bird which is figured on plate LX of my preliminary report on Sikyatki (_op. cit._). That portion of the wing which reproduces the wing feathers is shown in figure 4, and its resemblance to the feathers on figure 5 will, I think, be evident at a glance.[12] On several of the food basins from Sikyatki we find two or more feathers of this kind represented as hanging from a ring-shape or crescentic figure. One of the former is represented in plate LXI of the Smithsonian Report for 1895. The latter symbol has come down to modern times, and the figure painted on a shield of the Soyaluña ceremony, represented in color on plate CIV of my article on Tusayan Katcinas,[13] is almost an exact reproduction of the design on a Sikyatki food basin. This is one of several symbols on modern ceremonial paraphernalia which we can trace back over three hundred years by the aid of archaeology. [Illustration: 6 7]
