A similar jar in the British Museum was found in Warwick Square, London, inside a lead canister, and was originally filled with bone ashes. The Romans often reused glass jars, originally made for storing liquids and foodstuffs, as cremation vessels, but this kind of jar seems too fragile and was therefore probably purpose-made. The lead canister, which was found with the jar from London, protected the glass and bones. Georgio Sangiorgi is one of the most famous names associated with the field of ancient glass collecting. Working from the Galleria Sangiorgi in the Palazzo Borghese, Sangiorgi acquired the most magnificent collection of ancient glass, seeking only the finest examples.
