If the reader will walk with me from the theatre of Dionysus past the newly excavated site of the temple of Æsculapius, and past the Roman-Greek theatre which was erected by Hadrian or Herodes Atticus, I will show him what Plato meant. Of course, this later theatre, with its solid Roman back scenes of masonry, is equally interesting with the Theatre of Dionysus to the advocates of the unity of history! But to us who are content to study Greek Athens, it need not afford any irrelevant delays. Passing round the approach to the Acropolis, we come on to a lesser hill, separated from it by a very short saddle, so that it looks like a sort of outpost or spur sent out from the rock of the Acropolis. This is the Areopagus—Mars’ Hill—which we can ascend in a few minutes. There are marks of old staircases cut in the rock. There are underneath, on our left and right, as we go up, deep black caverns, once the home of the Eumenides. On the flat top there are still some signs of a rude smoothing of the stone for seats. Under us, to the north-west, is the site of the old _agora_, once surrounded with colonnades, the crowded market-place of all those who bought and sold and talked. But on the descent from the Areopagus, and, now at least, not much higher than the level of the market-place beneath, there is a small semicircular platform, backed by the rising rock. This, or some platform close to it, which may now be hidden by accumulated soil, was the old _orchestra_, possibly the site of the oldest theatre, but in historical times a sort of reserved platform, where the Athenians, who had their town bristling with statues, allowed no monument to be erected save the figures of Harmodius and Aristogiton, which were carried into Persia, replaced by others, afterwards recovered, and of which we may have a copy in the two fighting figures, of archaic character, now in the Museum of Naples. It was doubtless on this orchestra, just above the bustle and thoroughfare of the _agora_, that booksellers kept their stalls, and here it was that the book of Anaxagoras could be bought for a drachme.
