Fascinating world of ancient #glass: A #Roman glass model of a #boat, dating 2nd c. AD. It was found in St. Aldegund in a 4th-century woman's grave. Six of such boats are known. We don't know their function: Were they used as women's urinals, as components of water clocks and sundials, as drinking cups?
