Maniples were small, rectangular pieces of cloth worn by priests during the celebration of the Mass in the Roman Catholic Church. Traditionally, they were made of silk or linen and were often decorated with intricate designs. The maniples were worn on the left arm, symbolizing the priest's readiness to serve and perform sacred duties. In the context of the liturgical vestments, maniples were part of a set that included items like the chasuble and stole. Although their use has declined since the Second Vatican Council, they remain a historical element of the church's rich tradition and ceremonial practices.
