A small metal silver or gold rectangle, called a tama or an aphieroma, embossed with a facsimile of a leg, arm, eye, or what you may you need assistance with. This tama is to be placed on the altar or in front of the church icons. A tama combines a personal prayer and a vow to a saint while appealing for help or assistance. The petitioner vows to give or do something as he/she prays to a saint in times of need.
