Most, for example, those of the (modern) form ax 3 ± bx 2 ± cx = 0 were essentially quadratics (the solution x = 0 would not have counted); others, of the form ax 3 = bx + c;ax 3 = bx 2 + c or ax 3 = bx 2 + cx+d. were solved wrongly by simply applying the standard rules for quadratics. 99 Where Gerardi had treated ﬁfteen equation types, Dardi treated no fewer than 194, including some with fourth powers, all, however, reducible by a simple substitution to one of al-Khwārizmī's six basic forms. 100 Later authors repeated his rules for these equations as though they applied generally, without stating the special conditions under which they applied.
He also wrote a computus, a text on the reckoning of date and time, also in verse. 26 HOW ALGEBRA WAS ENTERTAINED AND CULTIVATED IN EUROPE Fig. 1 The ﬁnal verse of the Carmen de algorismo of Alexander Ville Dieu, and a multiplication table with a list of squares and cubes (Bodleian Library MS Savile 17, f. 108v). Usually known as the Massa computi it is internally dated at 1200,44 so his algorism may be supposed to date from roughly the same period. Even more inﬂuential than Ville Dieu's Carmen was the Algorismus of Johannes Sacrobosco (c.
8 Aldhelm (640–709), Abbot of Malmesbury and Bishop of Sherborne, was the author of Liber de septenario, a treatise on the number seven, but it was a mystical rather than mathematical work. 15 In England, Bede's learning was never more than a fragile candle in a vast surrounding darkness, and was all but extinguished in the invasions and instability of the three following centuries. Only early in the twelfth century did scholars in England and elsewhere across Europe become aware of the knowledge that all this time had been accumulating in Islamic Spain, and some of the more adventurous travelled south and brought back texts that were to set intellectual life in northern Europe on a new course.
