The religion of the Picts before their conversion is supposed by the majority of writers on this subject to have been that which prevailed in the rest of Britain and in Celtic Gaul, Druidism. The incredulous Burton, however, if we may judge from his History of Scotland,[88] as well as from an article of his in the Edinburgh Review, seems to believe that the whole system of Druidism has been elaborated by the imaginations of modern historians. That the Picts previous to their conversion had a religion, and a religion with what may be called priests and religious services, cannot be doubted, if we may trust Tacitus and Adamnan, the biographer of Columba; the former of whom tells us that, previous to the battle of the Grampians, the union of the various tribes was ratified by solemn rites and sacrifices, and the latter, that Columba’s efforts at conversion were strenuously opposed by the diabolical arts and incantations of the Magi. It appears from Adamnan that fountains were particularly objects of veneration; the superstitious awe with which many fountains and wells are regarded at the present day, being doubtless a remnant of the ancient Pictish religion. Trees, rivers, and lakes, as well as the heavenly bodies, appear also to have been objects of religious regard, and not a few of the customs which exist in Scotland at the present day have been inherited from our Pictish ancestors. Such are many of the rites performed on Hallowe’en, Beltane, Midsummer, &c., and many every-day superstitions still prevalent in the country districts of Scotland.
