It is also on this principle that the whole practice and doctrine of Sortilegy rest. Let us confine ourselves to that mode of sortilegy which is conducted by throwing open privileged books at random, leaving to chance the page and the particular line on which the oracular functions are thrown. The books used have varied with the caprice or the error of ages. Once the Hebrew Scriptures had the preference. Probably they were laid aside, not because the reverence for their authority decayed, but because it increased. In later times Virgil has been the favorite. Considering the very limited range of ideas to which Virgil was tied by his theme--a colonizing expedition in a barbarous age, no worse book could have been selected: [Footnote: '_No worse book could have been selected._'--The probable reason for making so unhappy a choice seems to have been that Virgil, in the middle ages, had the character of a necromancer, a diviner, &c. This we all know from Dante. Now, the original reason for this strange translation of character and functions we hold to have arisen from the circumstance of his maternal grandfather having borne the name of _Magus_. People in those ages held that a powerful enchanter, exorciser, &c., must have a magician amongst his _cognati_; the power must run in the blood, which on the maternal side could be undeniably ascertained. Under this preconception, they took Magus not for a proper name, but for a professional designation. Amongst many illustrations of the magical character sustained by Virgil in the middle ages, we may mention that a writer, about the year 1200, or the era of our Robin Hood, published by Montfaucon, and cited by Gibbon in his last volume, says of Virgil,-- that '_Captus a Romanis invisibiliter exiit, ivitque Neapopolim_.'] so little indeed does the AEneid exhibit of human life in its multiformity, that much tampering with the text is required to bring real cases of human interest and real situations within the scope of any Virgilian sentence, though aided by the utmost latitude of accommodation. A king, a soldier, a sailor, &c., might look for correspondences to their own circumstances; but not many others. Accordingly, everybody remembers the remarkable answer which Charles I. received at Oxford from this Virgilian oracle, about the opening of the Parliamentary war. But from this limitation in the range of ideas it was that others, and very pious people too, have not thought it profane to resume the old reliance on the Scriptures. No case, indeed, can try so severely, or put upon record so conspicuously, this indestructible propensity for seeking light out of darkness--this thirst for looking into the future by the aid of dice, real or figurative, as the fact of men eminent for piety having yielded to the temptation. We give one instance--the instance of a person who, in _practical_ theology, has been, perhaps, more popular than any other in any church. Dr.
