This paper seeks to explore the similarities between different unidentified texts, chiefly London, Wellcome Library MSS 404 and 5262, which are catalogued as a leechbook and a recipe collection, respectively. For the purpose, a brief description of each text will be first provided; then, the recipes in these texts will be analysed and their connections will be highlighted with a view to casting some light on possibly shared material and textual tradition.Universidad de Málaga.
