This Roman Odeion was built in 161 AD. by the Roman consul Herodes Atticus. Pausanias pays no attention to it in his book on Attica, because – he says – he had already completed his book on Attica before the Odeion was built. Herodes Atticus was the son of a very rich man from Marathon, who sponsored construction projects throughout Greece like a true maecenas, including the stadium in Delphi, the stadium in Athens (the kallimarmaro, which he had fitted with marble benches) and this Odeion under the Acropolis. He had it cut out of the rocks on the west side of the south slope of the Acropolis, in memory of his wife, who died in 160 AD. died. A reconstruction of the building with a partial canopy is given below (from ANCIENT GREECE, “Muses Publishers”).
