:’) I don’t think Schliemann had anything to do with the horse — I believe that’s a fairly recent (last 20 years) addition to give the tourists something to do. Also, the only part Schliemann excavated was the citadel of the city — the contemporary excavations did indeed find a large Mycenaean-era town under the Roman and Greek towns which sprawled out around the citadel.
Of course Schliemann had nothing to do with the horse. I was being sarcastic.
