During the Medieval Era Aquamanilles were vessels shaped like animals or human's riding horses. These were used for pouring liquids. During feasts servants poured liquid on diners hands for washing, then offered a linen towel for drying. In the churches they were used for religious ritual. The wealthy churches and most wealthy hosts used metal aquamanilles. The middle class, in attempts to emulate the wealthy had aquamanilles made of ceramic. There are extant examples of these found in many museums.
My research has also found some wonderful aquamanilles in the Middle East and in the Far East.
My reenactment aquamaniles are here:
I saw this aquamanille in the L.A.C.M.A. It was made in Syria in the 10th Century.
You will see examples of Ram Aquamanilles in the Victoria and Albert.
Another little Ram, this one has found a home.
Different attitudes on these aquamanilles.
A friend bought this one from me, so I get to see it on occasion.
