An exceptionally crafted Roman bowl cut from a single block of glass has set a record at auction in London this week, fetching £2,646,650. The sum is the most ever paid for a piece of ancient glass. “The Constable-Maxwell cage-cup dates from the third century and is decorated with a delicate lattice design. It has survived intact for 17 centuries. It is the third time the item has set the record for the highest price paid for a piece of ancient glass.”
