The Portland Vase is a first-century Roman glassvase, which served as an inspiration to many glass and porcelain makers from about the beginning of the 18th century onwards.
On February 7, 1845, the vase was shattered to pieces by one William Lloyd, who had drunkenly thrown a nearby sculpture on top of the case smashing both it and the vase to pieces.
The vase was pieced together, with fair success, but after the Duke's descendants sold the vase to the museum in 1945, a second and better reconstruction was done.
