Today’s manuscript is another Book of Hours “Heures à l’usage de Paris”, made in the same place at the end of the 15th century. The document is being kept in the Bibliothèque Mazarine, Paris. 
In the ‘calendrier’ for November, folio 11r, the border is illustrated with a highly stylised snail. The shell seems turrited but lacks any resemblance with a known species, and its coiling is indeterminate; the yellowish animal has two tentacles and a humanised face.
