The first layer of rubbish rests on the rock itself, and may very well have belonged to the town built by Dardanus, of which Tlepolemus relates the destruction by his grandfather Hercules.42 According to the Homeric story six generations, and according to generally accepted modern calculations two centuries, separate Dardanus from Priam. If therefore we accept 1200 B.C. as the date of the Trojan war, the town built by Dardanus would date from 1400 B.C., and we should possess data, if not absolutely certain, at least approximately so.43 There remain but a few relics of the buildings erected by the first inhabitants of the bill of Hissarlik, which relics consist of great blocks of irregular size, with remains of bearing walls composed of small stones cemented together with clay and faced with a glaze which has withstood the wear and tear of centuries. The second town, which would appear to have been that described in the Iliad, was probably built by a race foreign to those who erected the first. The hill, which was to become the Acropolis of the new town, was surrounded by the new-comers with a wall several feet thick, of which the foundations consisted of unhewn stones; whilst the upper part was made of artificially baked bricks, the baking having been done after they were put in place, by large fires lit in vacant places left at regular intervals; an arrangement recalling what we have said in speaking of vitrified forts.44 It is also interesting to note a similar mode of construction at Aztalan in Wisconsin in structures which probably date from the time of the Mound Builders. The walls at Hissarlik were protected by re-entering angles and projecting forts. The interior of the _enceinte_ was reached by three doors, and it is still easy to make out the ruins of the different buildings. A room sixty-five feet long by thirty-two wide is surrounded by very thick walls, and towards the southeast is a square vestibule, opening into the room by a large door.45 These, Dr. Schliemann thinks, were the _naos_ and _pronaos_ of a temple dedicated to the tutelary gods of the town. Quite close to them is another building with similar dispositions; a square vestibule giving access to a large room, which in its turn leads to a smaller apartment. These two buildings, which are reached through a _propylæum_, are the only ones of which the explorers have been able to make out the measurements with any exactitude.
