The zucchetto is a small, round skullcap, typically made of silk or other fine fabric. In Catholic worship, it's a sacred object used in liturgy by clergy and certain religious. Its color often matches the liturgical season. The zucchetto is simply placed on the head; it has no ritualistic actions associated with its use. While there's no explicitly stated symbolic meaning directly connected to its shape or material, its use denotes clerical status within the context of Catholic worship. It's a sign of office, a visual marker within the liturgical setting.
