progress of Patrick and Saint Columba by raising clouds and mist. Before the battle of Culdremne (561 CE) a druid made an airbe drtiad ("fence of protection"?) round one of the armies, but what is precisely meant by the phrase is unclear. The Irish druids seem to have had a peculiar tonsure. The word druí is always used to render the Latin magus, and in one passage St Columba speaks of Christ as his druid. Similarly, a life of Saint Beuno states that when he died he had a vision of "all the saints and druids". Sulpicius Severus' vita of Martin of Tours relates how Martin encountered a peasant funeral, carrying the body in a winding sheet, which Martin mistook for some druidic rites of sacrifice, "because it was the custom of the Gallic rustics in their wretched folly to carry about through the fields the images of demons veiled with a white covering". So Martin halted the procession by raising his pectoral cross: "Upon this, the miserable creatures might have been seen at first to become stiff like rocks. Next, as they endeavoured, with every possible effort, to move forward, but were not able to take a step farther, they began to whirl themselves about in the most ridiculous fashion, until, not able any longer to sustain the weight, they set down the dead body." Then discovering his error, Martin raised his hand again to let them proceed: "Thus", the hagiographer points out, "he both compelled them to stand when he pleased, and permitted them to depart when he thought good." Romanticism and later revivals From the 18th century, England and Wales saw a revival of interest in the druids. John Aubrey (1626–1697) had been the first modern writer to (incorrectly) connect Stonehenge and other megalithic monuments with the druids; since Aubrey's views were confined to his notebooks, the first wide audience for this idea were readers of William Stukeley (1687–1765). It is incorrectly believed that John Toland (1670–1722) founded the Ancient Druid Order; however, the research of historian Ronald Hutton has revealed that the ADO was founded by George Watson MacGregor Reid in 1909. The order never used (and still does not use) the title "Archdruid" for any member, but falsely credited William Blake as having been its "Chosen Chief" from 1799–1827, without corroboration in Blake's numerous writings or among modern Blake scholars. Blake's bardic mysticism derives instead
