The Abbot of St. Bertin, therefore, did not hesitate to keep in his private library more than one volume which he would not have willingly lent to the simple monks under his charge; nor to Torfrida either, had she not acquired so complete a command over the good old man, that he could deny her nothing.
So she read of Gerbert, Pope Silvester II., who had died only a generation back: how (to quote William of Malmesbury) “he learned at Seville till he surpassed Ptolemy with the astrolabe, Alcandrus in astronomy, and Julius Firmicus in judicial astrology; how he learned what the singing and flight of birds portended, and acquired the art of calling up spirits from hell; and, in short, whatever--hurtful or healthful--human curiosity had discovered, besides the lawful sciences of arithmetic and astronomy, music and geometry”; how he acquired from the Saracens the abacus (a counting table); how he escaped from the Moslem magician, his tutor, by making a compact with the foul fiend, and putting himself beyond the power of magic, by hanging himself under a wooden bridge so as to touch neither earth nor water; how he taught Robert, King of France, and Otto the Kaiser; how he made an hydraulic organ which played tunes by steam, which stood even then in the Cathedral of Rheims; how he discovered in the Campus Martius at Rome wondrous treasures, and a golden king and queen, golden courtiers and guards, all lighted by a single carbuncle, and guarded by a boy with a bent bow; who, when Gerbert’s servant stole a golden knife, shot an arrow at that carbuncle, and all was darkness, and yells of demons.
All this Torfrida had read; and read, too, how Gerbert’s brazen head had told him that he should be Pope, and not die till he had sung mass at Jerusalem; and how both had come true,--the latter in mockery; for he was stricken with deadly sickness in Rome, as he sang mass at the church called Jerusalem, and died horribly, tearing himself in pieces.
Which terrible warning had as little effect on Torfrida as other terrible warnings have on young folk, who are minded to eat of the fruit of the tree of knowledge of good and evil.
So Torfrida beguiled her lonely life in that dull town, looking out over dreary flats and muddy dikes, by a whole dream-world of fantastic imaginations, and was ripe and ready for any wild deed which her wild brain might suggest.
