58 AN ANDEAN MEDAL. 



an inch in thickness. On the edge it is smooth though 

 rather uneven, being in some places slightly rounded, and 

 in others more sharp or angular. Foldings in the metal, 

 such as would be produced by hammering, appear here 

 and there on the surface. The faces are not quite true 

 planes, and the curves in outline, as in sculptures, are not 

 quite regular but nearly so. On the face the ornamenta- 

 tion is all excavated or depressed, represented by the lines 

 and dots in figure 1. The other side, figure 2, has the 

 lines incised while the raised portions, marked by the dots, 

 are caused by the depressions on the front. Except in 

 case of the concavities of the face and the convexities of 

 the back, which were formed by the same strokes, each 

 line or mark on either side was independently engraved. 



The most ornate side, the face or front, fig. 1, has a 

 shallow round depression in the centre, circumscribed by 

 a circle an eighth of an inch in diameter. Around the 

 circle there are four semicircles, arranged so as to remotely 

 resemble the petals of a flower, and within each there are 

 four or five short lines extending outward from the circle. 

 Outside of these semicircles there is a second circle, nearly 

 three-eighths of an inch in diameter, around which are 

 placed fourteen elongate depressions, separated and en- 

 closed by lines that curve around the outer and larger end 

 of each. A larger circle fifteen-sixteenths of an inch across 

 is cut near the edge ; at the inside of this there are twenty- 

 seven subequal, subrouud depressions, each of them en- 

 closed by a curved line. Radiating from the large circle 

 to the edge of the disk there is a border formed of a hun- 

 dred and ten short lines. Each of the lines in this milling 

 was made in part by a tool having a comparatively broad 

 edge and its excavation was then continued to the margin 

 by a narrower implement. 



Turning to the back, fig. 2, we find the convexities pro-
