Seen in a few illustrations of feasts and eating utensils are aquamaniles -- a sort of pitcher used for hand-washing. Typical forms are animals, mounted knights or horsemen, and fantasical monsters; most of the surviving examples seem to be metal, but there are several ceramic examples too. (More information can be found in the Florilegium; The Art of the Medieval Aquamanile is also interesting.)

Lions, Dragons, and Other Beasts: Aquamanilia of the Middle Ages, Vessels for Church and Table, an exhibit of the aquamaniles from the Met (several of which are also linked below), was on display at The Bard Graduate Center for Studies in the Decorative Arts, Design, and Culture a few years ago.

Frsart in Lige. Also, Cleveland 1965.22. A similar aquamanile appears in the center panel of the Mérode Altarpiece; I'm unsure whether this is meant only as a symbol of Mary's chastity & purity (as the ewer & basin in Campin's Werl Altarpiece and Madonna and Child or this detail of van der Weyden's Annunciation Triptych), or if it's meant to be seen as a typical element of 15th century Flemish domestic interior. Also V&A M.2669-1931, M.2676-1931, M.2-1937.

Since I've had a few inquiries on where one can obtain aquamaniles ...

• Poterie du Carbassou Rasigures has a rather giraffe-like aquamanile.
• Raku Raku Tei has a lion aquamanile; I suspect that the mounted knight, owl, and fish in the Gallery section may also be intended for use as aquamaniles, but I am unsure if they are based on historical examples.
• StarHammer Arts Magickal's website seems to have disappeared; contact information for the proprietor, Meistari Hroar Stormgengr, can be found here.
• The Töpferei-Museum Langerwehe sells a beast-shaped aquamanile.
• Trinity Court Potteries sell aquamaniles in the shape of a ram, stag, or man on horseback.
• Got deep pockets? You might be able to find 19th century repros of some of the medieval metal aquamaniles, like the bronze lion-shaped aquamanile at Roy Precious Antiques & Fine Art
