the monument seems likely to have been a Saxon erection, during their days of paganism; for it is neither mentioned by Cæsar nor Tacitus, who were both likely to have noticed a structure of so remarkable an appearance. Leaving the book to return to the author, I am sorry to add, that this learned man, after being president of the College of Physicians, and thus having attained the highest honours of his profession, in 1691 fell into embarrassed circumstances, which forced him shortly after to take refuge in the island of Jersey. It is uncertain if Dr Charleton ever returned from this sort of exile; but his death took place in 1707, at the advanced age of eighty-eight years. Dr Charleton's hypothesis concerning Stonehenge was but indifferently received. It was considered as a personal attack on Inigo Jones, who had formed a much more fantastic opinion upon the subject, conceiving the stones to form a temple, dedicated, by the Romans, to the god Cælus, or Cælum. To the disgrace of that great architect's accuracy, it seems probable that he never had seen the monument which he attempts to describe; for he has converted an irregular polygon into a regular hexagon, in order to suit his own system. Dryden sided with Charleton in his theory; and, in the following elegant epistle, compliments him as having discovered the long-forgotten cause of this strange monument. The verses are not only valuable for the poetry and numbers, but for the accurate and interesting account which they present of the learning and philosophers of the age. It was probably written soon before the publication of Charleton's book in 1663. Sir Robert Howard also favoured Dr Charleton with a copy of recommendatory verses. Both poems are prefixed to the second edition of the "Chorea Gigantum," which is the only one I have seen. That of Dryden seems to have been afterwards revised and corrected. EPISTLE THE THIRD.
