Pisa - Museo dell'Opera del Duomo

This museum holds a large collection of the works of art. Here are the originals, many of which are meanwhile replaced with replicas all around he Piazza dei Miracoli, as many of them crumbled and weathered. The museum is well worth a visit, but was closed (for a year?) in autumn 2014.

Following the information given, this ivory casket was produced in the Byzantine Empire within the 11th century.

This side shows, that the hare got caught by the lion (see previous upload), maybe the griffin waits for his share of the prey.

The nude "dancers" here hold musical instruments.
