Crosses were commonly worn as jewelry, the functions of which were two: to beautify and protect from harm. The most common type in the Holy Land during the Byzantine period was a small bronze pendant decorated with circles. Many crosses of this type were discovered in tombs, where they were presumably placed along with personal belonging of the deceased.
