This case takes the form of the vessel for which it was made, an Octagonal tray with interlaced foliate decoration (O106). The exquisite pieces from the Dauphin´s Treasure are complemented by the custom-made cases that match the shape of each and allow them to be safely transported and counted, as each can be recognized by the contours of its corresponding box. Their wooden structures are lined with wool and silk or taffeta, and they are held shut by a system of fasteners. Most are covered, on the outside, with red Morocco leather adorned with bookbinding motifs, such as fleurs-de-lis, dolphins, cartwheels rosettes and so on. This exterior decoration may have been carried out in the last third of the 17th or beginning of the 18th century at the workshops that bound the Dauphin´s book in Paris, either as cases for newly acquired pieces or to replace overly worn cases, or possibly to create a uniform appearance for the entire collection.
