Triquetra Altar Tile

The Pentacle or Paten disc is an altar consecration tool with a sigil or magical symbol engraved or inscribed upon it. The most common symbol is a pentagram within a circle, specifically a pentacle, although some other symbols may be used such as the triquetra. The disc symbolizes the element earth. It is typically used to represent the element of Earth during evocation, as a symbol which blesses items, as well as magically energizing that which is placed upon it.
