Le Plongeon discovered a fragment of a stone slab in the ancient Maya city of Mayapan, of which he published a description in the Proceedings of the American Antiquarian Society. It contains an ogee Swastika (tetraskelion), with ends curved to the left and an inverted [U] with a wheel (fig. 261). Le Plongeon believed it to be an Egyptian inscription, which he translated thus: The character, inverted [U], stood for _Ch_ or _K_; the wheel for the sun, _Aa_ or _Ra_, and the Swastika for _Ch_ or _K_, making the whole to be _Chach_ or _Kak_, which, he says, is the word _fire_ in the Maya language.[264] [Illustration: Fig. 261. FRAGMENT OF STONE SLAB FROM THE ANCIENT MAYA CITY OF MAYAPAN. Ogee Swastika (tetraskelion). Proceedings of the American Antiquarian Society, April 21, 1881.] COSTA RICA. A fragment of a metate (Cat. No. 9693, U. S. N. M.) found on Lempa River, Costa Rica, by Capt. J. M. Dow, has on its bottom a Swastika similar to that on the metate from Nicaragua. Specimen No. 59182, U. S. M. N., is a fragment of a pottery vase from Las Huacas, Costa Rica, collected by Dr. J. F. Bransford. It is natural maroon body color, decorated with black paint. A band two inches wide is around the belly of the vase divided into panels of solid black alternated with fanciful geometric figures, crosses, circles, etc. One of these panels contains a partial Swastika figure. The two main arms cross at right angles in Greek form. It is a partial Swastika in that, while the two perpendicular arms bend at right angles, turning six times to the right; the two horizontal arms are solid black in color, as though the lines and spaces had run together. SOUTH AMERICA. BRAZIL. The leaden idol (fig. 125) (Artemis Nana[265] of Chaldea, Sayce; statuettes of the Cyclades, Lenormant) found by Dr. Schliemann in the third, the burnt city of Hissarlik, Troy, was described (p. 829) with its Swastika on the triangular shield covering the pudendum, with the statement that it would be recalled in the chapter on Brazil. The aboriginal women of Brazil wore a triangular shield or plaque over their private parts. These shields are made of terra cotta, quite thin, the edges rounded, and the whole piece rubbed smooth and polished. It is supported in place by cords around the body, which are attached by small holes in each angle of the triangle. The U. S. National Museum possesses several of these plaques from Brazil, and several were shown at the Chicago Exposition.
