One of the aspects of Roman culture that is exceedingly rare but also extremely beautiful is glassware. Several museums have excellent collections, including the Getty Museum in Malibu. This is a bowl from Pompeii in the National Museum in Naples. One of the things that happens with glass buried for centuries is that it can develop an iridescence, a sort of rainbow-like mineralized coating, which has a particular beauty of its own and is often prized by collectors. It’s hard to pick it up in a photograph, particularly when the lighting isn’t very good, but you can see some indication of it here.
