Among Heinrich Schliemann’s discoveries of architecture at Mycenaean Tiryns in the Argolid Plain in southern Greece, one of the most impressive was a single huge rectangular stone slab that covered the floor of a relatively small square room. The slab’s surface was smoothed down and provided with drilled sockets to anchor a wooden dado. The slab was tilted slightly to provide a slope for water to run off through a carved trough and surely served as an unusual floor for a room devoted to bathing, not far from the Throne Room of the palace. This article deals with the bathing room and, in particular, a proposed wooden bench built along its side walls. It also investigates what we know about bathing in the Aegean during the Late Bronze Age.
