As to the "treatment of the sun," we find faces with rays, or divergent
curves, in Schoolcraft, vol. i., p. 362, figs. 16 and 17, and p. 409,
fig. 9; vol. iii., p. 493,--a circle with rays in the rock inscription
(Delaware perhaps) on the Susquehanna near the Maryland line, a face
without rays in the rock inscription (also Delaware, possibly) at Safe
Harbor on the Susquehanna, and a face with rays, the counterpart of the
carving in question, on a small broken tablet found near Akron, Ohio,
in the collection of the late Mr. Dupont, of Philadelphia, who had no
doubt of its authenticity.
