Mr. Story Maskelyne considers the Greeks reformed the Temple later on. “Within 500 years of the latest of the above-mentioned dates the Phœnician or Tyrian Empire had ceased to exist, and her numerous colonies had been absorbed by the nationalities surrounding them. About B.C. 400 the Greeks supplanted the Phœnicians in their trade with Britain, and probably for some time continued to use the same mart and sea route the latter had used—we may assume from Cherbourg to Poole or Christchurch, whence they bore away the tin in their coracles from Cornwall. Now commenced a new era for Stonehenge. It must have been a noted Temple, and I cannot doubt that Hecatæus did allude to it as cited by Strabo, when he wrote, in the sixth century B.C., of the Round Temple to Apollo in the land of the Hyperboreans. Now the festivals of the Greeks were more connected with the months than with the year, and their calendar months were alternate, full and hollow, where the thirty pillars were doubtless used by them for the daily sacrifice in the months of thirty days and the spaces between them, omitting the entrance, for the hollow months, of twenty-nine days. Owing to the precession of the stars, Stonehenge no longer answered some of the purposes for which it has been founded. The Greeks had adopted with ardour the Metonic Cycle discovered by them B.C. 430, and they reformed the old Sun Temple by the addition of the inner horseshoe of blue stones which represented that Cycle, for they were in number nineteen. As to how, or why, the blue stones came to be imported, I imagine they are native to Brittany or Normandy, whence they might easily have been brought as ballast in Greek ships, which took back tin in their stead from Poole or Christchurch, and from the latter port they might easily have been taken in rafts to Amesbury.” [Picture: The stone and flint implements discovered at Stonehenge during the excavations in 1902] [Picture: Hele Stone] THE DATE OF STONEHENGE.
