Abstract

This paper summarizes the results of the earlier phase (1991–8) of geoarchaeological investigations at the Canal of Xerxes in northern Greece and then presents the findings of recent work. Through the combination of geophysical survey and analysis of sediments obtained from bore holes drilled along the supposed course of the canal it was established in 1996 that at least in the central sector of the 2 km wide isthmus there was indeed a deeply buried trench-like structure, c. 30 m wide. This is most likely to have been a canal that would have had a depth of water of up to 3 m. The recent work has explored first the situation at the southern end of the canal where one ancient writer claimed that the terrain would only have allowed the construction of a slipway (diolkos). However, seismic survey and sedimentological analysis of cores in that area found no obstacle to the digging of a canal. Second, the results of seismic survey (supported by the evidence of satellite imagery) at the northern end of the canal have suggested that its course was more easterly than that proposed earlier on the basis of the line of present-day lowest ground. In sum, all the indications are that there was a canal across the Athos peninsula and not a diolkos, and that the canal's features conform to those outlined by Herodotus in his description of the structure built by Xerxes to allow the Persian fleet into the Aegean for the invasion of Greece in 480 BC.

19 For instance in the 120 m profile at right angles across the canal where borehole (BH) 2 was located a 600 nT negative anomaly of some 50 m width was found; this has not yet been explained.

22 Drilled by Mr N. Nezis of Technodrill, Eleusis. As before, the core cylinders were split down their central axis and allowed to dry for almost ten weeks. They were examined macroscopically at Nea Roda before samples were taken to Thessaloniki for analysis.

23 Unfortunately it was not possible to drill BH 5 down to the crystalline basement in order to clarify the exact depth of the older torrent incision.

24 Furthermore, GS, who has some twenty years' field experience in the area, has not located any such solid rock exposure.

26 Recent settlement has gradually filled this area with debris in order to make it suitable for building on.
