In this post I will show you some of the carved ivory objects from the Middle Ages. Some of them are well known and have been reproduced in books on medieval craft, but not all.
Ivories can be good sources to clothing, even if they're monochrome, because the three-dimensional quality makes it possibel to see folds and wrinkles better. Especially for, say the 11th and 12th cnetury, that is improtant, because otherwise one could mistake the lines at wrists and ankles for stripes, insted of folds, or scrunched up fabric.
