[160] _Opera_, tom. i. p. 119. Cardan here calls him "Gulielmus _Lataneus_ Anglus adolescens mihi charissimus." In the _De Morte_, however, he speaks of him as "ex familia Cataneorum" (see last page). [161] Cardan writes (_De Subtilitate_, p. 444) that Suisset [Richard Swineshead], who lived about 1350, was known as the Calculator; but Kaestner [_Gesch. der Math._ I. 50] maintains that the title Calculator should be applied to the book rather than to the author, and hints that this misapprehension on Cardan's part shows that he knew of Suisset only by hearsay. The title of the copy of Suisset in the British Museum stands "Subtilissimi Doctoris Anglici Suiset. Calculationes Liber," Padue [1485]. Brunet gives one, "Opus aureum calculationum," Pavia, 1498. CHAPTER VIII CARDAN travelled southward by way of the Low Countries. He stayed some days at Antwerp, and during his visit he was pressed urgently to remain in the city and practise his art. A less pleasant experience was a fall into a ditch when he was coming out of a goldsmith's shop. He was cut and bruised about the left ear, but the damage was only skin-deep. He went on by Brussels and Cologne to Basel, where he once more tarried several days. He had a narrow escape here of falling into danger, for, had he not been forewarned by Guglielmo Gratarolo, a friend, he would have taken up his quarters in a house infected by the plague. He was received as a guest by Carlo Affaidato, a learned astronomer and physicist, who, on the day of departure, made him accept a valuable mule, worth a hundred crowns. Another generous offer of a similar kind was made to him shortly afterwards by a Genoese gentleman of the family of Ezzolino, who fell in with him accidentally on the road. This was the gift of a very fine horse (of the sort which the English call Obinum), but, greatly as Cardan desired to have the horse, his sense of propriety kept him back from accepting this gift.[162]
