CHAPTER III.
PETROGLYPHS IN CENTRAL AND SOUTH AMERICA.
Some writers have endeavored to draw definite ethnic distinctions between the pre-Columbian inhabitants of North America and those farther south. The opinions and theories which have favored such discriminations have originated in error and ignorance. Until lately there has been but scanty scientific investigation of the peoples of Central and South America and but a limited exploration of the regions now or formerly occupied by them. The latest opinion of the best ethnologists is that no sufficient reason can be shown for separate racial classification of the aborigines of the three Americas. The examples of petroglyphs now presented from Central and South America, all of which are selected as typical, show remarkable similarity to some of those above illustrated and described, especially to those in California, New Mexico, and Arizona. This topic is further discussed under the heading of Special Comparison, Chapter [XX], infra.
SECTION I.
PETROGLYPHS IN CENTRAL AMERICA.
NICARAGUA.
Dr. J. F. Bransford (a) gives the following account:
On a hillside on the southern end of the island of Ometepec, Nicaragua, about 1½ miles east of Point San Ramon, are many irregular blocks of basalt with marks and figures cut on them. The hillside faces east, and is about half a mile from the lake. There were similar markings on many of the shore rocks, which, in May, were partially covered with water, notwithstanding that that was about the driest season. These markings were excavated about half an inch in depth and a little more in width. Human faces and spiral lines predominated. There was also a crown, a representation of a monkey, and many irregular figures.
Several illustrations from these rocks are presented, infra, in Figs. [1102] and [1103], and one is reproduced in this connection as Fig. 104.
