it looks very similar to image 31 from Sarpellon's book. The text says in relation to the image that the main use for these rosetta canes were as chevron beads but that they are also found enclosed in small spheres of clear glass (cristallo) or as vessels/jugs (brocchette). Very few of these objects are known and they are usually dated between the 15th and the beginning of the 16th centuries.

Image 31 is referred to as a bead containing fragments of rosetta cane and gold leaf and is dated to the end of the 15th century. It was found in the Venice lagoon.

Franchini produced a giant bead (88mm in diameter) image no. 555 which also has some similarities though it uses a much greater variety of millefiori murrine (mostly not rosetta)and trailed decoration. Unlike Degumeh's bead and the Peruvian bead, none of the millefiori murrine are used longitudinally.

Does anyone know whether it is permissible to photograph and post an image from a published work? Is it necessary to get the permission of the copyright holder/s?
