Ornamental bronze pins are another example of Luristanian bronze work employing animal imagery. The Dallas Museum of Art ram-headed example was cast by the lost-wax method in five pieces (each pair of horns, each animal head, and the pin itself). Horizontal pins appear as often as vertical pins in Iranian art and were probably used to pin large sections of garments together. The double curve of the two pairs of animal horns is especially elegant.
