An altar cloth is a piece of fabric used to cover the altar in a place of worship, such as a church or temple. It serves both a decorative and functional purpose, enhancing the appearance of the altar while also protecting it from wear and tear. Altar cloths can be made from various materials, including linen, silk, or cotton, and often feature religious symbols or colors that correspond to specific liturgical seasons. These cloths are typically changed according to the church calendar, reflecting different themes or celebrations. For example, during Advent, the altar cloth may be purple, while during Easter, it might be white or gold. The use of altar cloths is common in many religious traditions, including Christianity and Judaism.
