Lavabo

at the Cloisters Museum in NYC

Made from Limestone from the region of Burgundy, France in the 13th century,

Originally from the chapel of Sainte-Catherine at Montbellet, near Macon.

The Ernest Brumer Family gifted it to the Cloisters Museum in 1948.

This lavabo ( from the Latin for "I will wash") has two basins; presumably, one was intended for washing hands and the other for washing Eucharistic vessels, which could then be placed on the shelf above (The Cloisters).
