Many of the antiquities which are scattered over the north of Scotland, such as stone circles, monoliths, sculptured stones, rocking stones, &c., are very generally supposed to have been connected with religion. From the resemblance of the circles especially, to those which exist in South Britain and in France, it has been supposed that one religion prevailed over these countries. As Druidism is so commonly believed to have prevailed among the Picts as well as among the other inhabitants of Britain, we shall here give a very brief account of that system, chiefly as we find it given in Cæsar.[90] The following is the account given by Cæsar of the character and functions of the Druids:--“They attend to divine worship, perform public and private sacrifices, and expound matters of religion. A great number of youths are gathered round them for the sake of education, and they enjoy the highest honour in that nation; for nearly all public and private quarrels come under their jurisdiction; and when any crime has been committed, when a murder has been perpetrated, when a controversy arises about a legacy, or about landmarks, they are the judges too. They fix rewards and punishments; and should any one, whether a private individual or a public man, disobey their decrees, then they exclude him from the sacrifices. All these Druids have one chief, who enjoys the highest authority amongst them. When he dies, he is succeeded by the member of the order who is most prominent amongst the others, if there be any such single individual; if, however, there are several men equally distinguished, the successor is elected by the Druids. Sometimes they even go to war about this supremacy. “The Druids take no part in warfare; nor do they pay taxes like the rest of the people; they are exempt from military service, and from all public burdens. Attracted by such rewards, many come to be instructed by their own choice, while others are sent by their parents. They are reported to learn in the school a great number of verses, so that some remain there twenty years. They think it an unhallowed thing to commit their lore to writing, though in the other public and private affairs of life they frequently make use of the Greek alphabet.... Beyond all things, they are desirous to inspire a belief that men’s souls do not perish, but transmigrate after death from one individual to another; and besides, they hold discourses about the stars, about the size of the world and of various countries, about the nature of things, and about the power and might of the immortal gods.”
