The history of science records the existence of sublimators in the Byzantine world from the time of the Lower Empire, but none are known to exist in material form, the oldest being one described in a 13th century manuscript. A growing number of brass pieces have been brought to the Museum, and their chronological attribution to the 9th century AD is certain. A ceramic piece found in the excavations at Pechina (Almería) allows us to simulate its use and date.
