What type of metalwork sculpture is pictured below?

A baptismal font

Explanation:

The Baptismal Font at St. Bartholomew's Church is a well-known example of Mosan art.  Even though the Mosan origin of the font has been challenged, the font is still credited to Reiner of Huy, a 12th-century metalworker, and sculptor. The font was created through the lost-wax casting technique, and includes illustrations of five scenes, such as the Baptism of Christ and St. Peter baptizing Cornelius the Centurion.
