The story of the Irish origin of Stonehenge was repeated a generation after Geoffrey by Giraldus Cambrensis in his Topographia Hibernica (1187). Loomis adds, "Chroniclers repeated the tale and successive generations believed, to borrow Spenser's wording, that they could 'Th'eternall marks of treason... at Stonheng vew.' (F. Q.,II, x, 66)." The earliest known mention of Stonehenge was by Henry of Huntingdon in 1130: ""Stanenges, where the stones of wonderful size have been erected after the manner of doorways, so that doorway appears to have been raised upon doorway; and no one can conceive how such great stones have been so raised aloft, or why they were built there."

Not a "survival" but a "revival" of the legend may be noted here, in a site promoting the novel Merlin Built Stonehenge.

According to Loomis, this story was first printed in 1724 and repeated in an 1821 publication. E. H. Wood (1924) thinks that it may have originated from a tale told to the author of the 1724 book, John Wood.

According to Loomis, "Geoffrey's Historia implies or states the following more or less factual elements: (1) Stonehenge was a great stone circle called the Giants' Dance; (2) it was used for a funerary monument though not originally erected for that purpose; (3) it was built of stones that were Stones of Worship, Mystici Lapides, (4) stones that were brought from afar; and (5) it was related in some way to the stone circles in Africa and Ireland. Since these statements or implications can now be shown to correspond to other megalithic legends or to certain facts known only in modern times in regard to megaliths in general and to Stonehenge in particular, it is evident that they could not have been invented by Geoffrey but must have been known to him through antecedent tradition."

As Voss puts it, ".. the public mind, having been conditioned by generations of authorities to see Stonehenge as a temple of the Druids, could hardly be blamed if it were somewhat less agile than that of the professors in turning against the Druid image."

Before it was bequeathed to the state in 1918 the Stonehenge property went through a succession of private hands, last selling for £6,600 in 1915. For a 50-year period in the mid-seventeenth century Sir Lawrence Washington, an ancestor of the American president, owned the property.
