The use of mosaic canes to simplify the production of eyes on glass beads was probably developed during the Hellenistic period. Before that time, eyes had been made by layering glass in different colors, creating what are known as stratified eyes. The newer technique was employed in combination with other decorative motifs, as can be seen in this large bead, which presents trails forming a geometric framework encasing the eyes. It was probably crafted in the Islamic world. Examples have been found in Syria and Iran. Islamic makers of glass beads had the skills necessary to produce multicolored canes, and they were known for their use of the trailing technique. This bead exemplifies the enduring use of the eye, which was incorporated into diverse cultures, made in complex patterns, and employed as a source of protection.
