Aedicula

In ancient Roman religion, an aedicula is a small shrine, and in classical architecture refers to a niche covered by a pediment or entablature supported by a pair of columns and typically framing a statue. Aediculae are also represented in art as a form of ornamentation. The word aedicula is the diminutive of the Latin aedes, a temple building or dwelling place. The Latin word has been Anglicised as "aedicule" and as "edicule".
