Drawing of a Scythian-type arrowhead. The shaded part (and the unshaded section just to the right) indicates a triangular fin, which is repeated on all three sides. That a fin is on all three sides is indicated by the section drawing on the left, which is in effect a view looking up the shaft of the arrowhead. The particular section shown is that cut on the large drawing on the right by the line between that drawing and the section drawing.
