Is this the earliest depiction of Stonehenge?

"Among the marginalia of the autograph manuscript of Gervase of Tilbury’s Otia Imperialia, Vatican lat. 933, f. 41rb (1210-1215) there are what Caldwell (Scriptorium 11, 1957, 91) calls ‘primitive looking pictures’, one of which, on f. 41rb, illustrates the Giants’ Ring with the inscription Conposita corea gigantum a Merlino."
