Byzantine Tetrapod - Catholic Stock Photo
A tetrapod is a small, four-legged table ('Tetra", meaning four, and "Pod", for foot) directly in front of the iconostasis (a solid screen of stone, wood, or metal, usually separating the sanctuary from the nave), upon which are placed holy icons for veneration. Upon entering the church, before receiving Communion, and prior to leaving the church, the faithful are invited to walk up to the tetrapod, cross themselves, and kiss the icons placed there.
