Abstract
Italian ms 63, now in the John Rylands Library, contains fifty-four images of monstrous births, both human and animal. The manuscript was probably completed in the mid-eighteenth century and was owned by Edward Davenport of Capesthorne Hall and later by the Manchester-based physician David Lloyd Roberts. This article explores the possible sources for some of the images, which range from descriptions or illustrations in well-known publications on monsters, to popular pamphlets, to drawings and paintings. An analysis of the choice of subject matter and the ways in which the source material has been used places the manuscript within eighteenth-century collecting practices and emphasises the multivalency of the monstrous.
