This Colonnade of Kotys we know was originally built of sun-dried brick, and may perhaps originally have had wooden columns. Sun-dried brick, so common in many parts of Greece to-day, was often used in ancient times for important purposes, as, for example, in the building of the Heræon at Olympia. When this somewhat perishable material was covered with a fine hard cement, which resisted the heaviest rain, walls so constructed became wonderfully durable. The Colonnade of Kotys was rebuilt during Roman times. Some of the roof tiles discovered lately bear the name of Antoninus. Cavvadias suggests that the small temple γ is that of Themis. _R_ in Plate I is a colonnade which extended east and west nearly at right angles with the Roman Baths _P_ described above. Plate XIII shows the remains of this colonnade, also a small open aqueduct with basins in its course about eleven yards apart. This small water channel reminds the visitor of a similar one existing in front of the Echo Colonnade at Olympia, the latter contains one or two basins like those shown in the plate. This view shows in the distance the Roman baths (_P_). Adjoining this colonnade on the north-east is a large quadrangle _S_, formerly bordered on its four sides by columns. Its length east and west was about double its breadth north and south. Was this another hostel? _T_ is believed by M. Cavvadias to be the Temple of Aphrodite, a Doric structure only excavated in 1892. An inscription discovered on the spot speaks of the sanctuary of Aphrodite; not far from it was found a statue of the goddess in Parian marble, a most beautiful figure now preserved in the Museum at Athens. Plate XIV is an attempt to represent this figure as it now exists. The ancient cemetery of the Hieron was near the point marked ε in Plate I. _U_ in Plate I is an Ionic building, the present condition of which is shown in Plate XV. It may be a temple external to the precinct, or it may, as others suggest, be the Northern Propylæa or Ceremonial Gateway. The latter appears the more probable explanation; by this entrance the pilgrims who came from the port of Epidaurus would approach the Sanctuary. Note the small well in the foreground. _V_ is a Roman building of unknown purpose, and _W_ represents a barrier which probably was the northern wall of the precinct. A wall protected the sacred enclosure on every side, “Τὸ δὲ ἱερὸν ἄλσος τοῦ Ἀσκληπιοῦ περιέχουσιν ὅροι πανταχόθεν,”[3] says Pausanias, but fully one-half of this barrier has yet to be found. It will be noted that, as at Olympia, many important buildings are external to the precinct. Plate XVI represents a side view of the theatre (which is not shown in the outline plan Plate I).
