AN ANDEAN MEDAL. 59 



duced in forming the depressions of the front to be very 

 noticeable, and to determine the design. A small circle is 

 not introduced in the centre ; the flower-like figure is ab- 

 sent. The inner circle on this side is a trifle more than 

 three-eighths of an inch in diameter. About the inner side 

 of it there is a series of twelve small; more or less irregu- 

 lar semicircles and from its outer side fourteen elongate 

 convexities radiate. The circle near the edge is a little 

 more than seven-eighths of an inch in diameter ; like its 

 counterpart on the face it has twenty-seven semicircles at 

 its inner side and from the outer the short lines of the mil- 

 ling, a hundred and sixteen in number, extend to the mar- 

 gin. In this border the lines were not made with the tool 

 used on the front; they are somewhat crescent-shaped, 

 deeper along the shorter edge. 



The two holes that disfigure the piece were made after 

 the engraving was completed, otherwise they would not 

 have interfered so much with the design. The smaller, 

 near the centre, appears to have been made some time be- 

 fore the other ; its burr, on each side, was hammered down 

 flat, while that of the larger and later was left prominent, 

 as would hardly have been the case if the larger had been 

 made first, or even if both had been made by the same 

 hand. These holes were formed by some tapering instru- 

 ment worked from both sides, the utensil throwing up a 

 rim on each and leaving the hole wider at each surface. 

 Neither of the perforations is quite round. Their purpose 

 must have been for attachment. Dissatisfaction with the 

 smaller, so near the middle of the disk, probably furnished 

 a reason for the existence of the larger. 



Differences in shapes and depths and occasional evidence 

 of slips of the graver in cutting prove that each line and 

 each depression was made separately. To make the con- 

 cavities the metal was driven down upon a hard but yield-
