  27. The Saros Cycle at Stonehenge Around 50 BC the Sicilian historian Diodorus described a temple often identified as Stonehenge: …“Hecateus [c 350 BC] and certain others say that in the region beyond the land of the Celts [Gaul] there lies in the ocean an island no smaller than Sicily. This island… is inhabited by the Hyperboreans… there is also on the island a magnificent sacred precinct of Apollo and a notable temple adorned with many votive offerings and spherical in shape. They also say how the moon viewed from this island appears to be but a little distance from the earth… the god visits the island every 19 years, the period in which the return of the stars [astron] to the same place in the heavens is accomplished; and for this reason the 19-year period is called by the Greeks the year of Meton” (Diodorus Siculus, II).
