This bowl was probably part of an 'accouchement' set, used to serve broths to women after childbirth; see Wendy M. Watson, Italian Renaissance Ceramics, The Howard I. and Janet H. Stein Collection and the Philadelphia Museum of Art (Philadelphia, 1001), pp. 138-140, for an example with scenes of childbirth, but of related form. An armorial cover of similar form in the Victoria and Albert Museum is illustrated by Bernard Rackham, Catalogue of Italian Maiolica (London, 1940), Vol. II, pl. 168, no. 1053, which Rackham describes as 'the tagliere from an accouchement set, forming also the lid of a bowl'.
A detail of the cover is illustrated at the end of the catalogue.
