He told of a place of fabulous wealth named Quivera, and, says the ancient historian: "He gave such a clear account of what he told, as if it was true and he had seen it, that it seemed plain afterward that the devil was speaking in him." Carried away by these glowing visions of wealth, Coronado sent Tovar back to San Hieronimo.
Tartaglia searched, and though he could not put his finger on any spot which showed that Messer Hieronimo had broken his oath, he found what must have been to him as a precious jewel, to wit a mistake in reckoning, which he reported to Cardan in these words: "In this process your excellency has made such a gross mistake that I am amazed thereat, forasmuch as any man with half an eye must have seen it indeed, if you had not gone on to repeat it in divers examples, I should have set it down to a mistake of the printer."
It had been told to Messer Hieronimo that Fiore's thirty questions had led up to a case of the cosa and the cubus equal to the numerus, and that Messer Niccolo had discovered a general rule for such case. Messer Hieronimo now especially desired to be taught this rule.
The receipt of this letter seems to have disquieted Tartaglia somewhat; for he has added a note to it, in which he says that Cardan has placed him in a position of embarrassment. He had evidently wished for an introduction to D'Avalos, but now it was offered to him it seemed a burden rather than a benefit. He disliked the notion of going to Milan; yet, if he did not go, the Marchese d'Avalos might take offence. But in the end he decided to undertake the journey; and, as D'Avalos happened then to be absent from Milan on a visit to his country villa at Vigevano, he stayed for three days in Cardan's house. As a recorder of conversations Tartaglia seems to have had something of Boswell's gift. He gives an abstract of an eventful dialogue with his host on March 25, 1539, which Cardan begins by a gentle reproach anent his guest's reticence in the matter of the rule of the cosa and the cubus equal to the numerus. Tartaglia's reply to this complaint seems reasonable enough (it must be borne in mind that he is his own reporter), and certainly helps to absolve him from the charge sometimes made against him that he was nothing more than a selfish curmudgeon who had resolved to let his knowledge die with him, rather than share it with other mathematicians of whom he was jealous. He told Cardan plainly that he kept his rules a secret because, for the present, it suited his purpose to do so. At this time he had not the leisure to elaborate farther the several rules in question, being engaged over a translation of Euclid into Italian; but, when this work should be completed, he proposed to publish a treatise on Algebra in which he would disclose to the world all the rules he already knew, as well as many others which he hoped to discover in the course of his present work. He concludes: "This is the cause of my seeming discourtesy towards your excellency. I have been all the ruder, perhaps, because you write to me that you are preparing a book similar to mine, and that you propose to publish my inventions, and to give me credit for the same. This I confess is not to my taste, forasmuch as I wish to set forth my discoveries in my own works, and not in those of others." In his reply to this, Cardan points out that he had promised, if Tartaglia so desired, that he would not publish the rules at all; but here Messer Niccolo's patience and good manners gave way, and he told Messer Hieronimo bluntly that he did not believe him. Then said Cardan: "I swear to you by the Sacred Evangel, and by myself as a gentleman, that I will not only abstain from publishing your discoveries if you will make them known to me but that I will promise and pledge my faith of a true Christian to set them down for my own use in cypher, so that after my death no one may be able to understand them. If you will believe this promise, believe it; if you will not, let us have done with the matter." "If I were not disposed to believe such oaths as these you now swear," said Tartaglia, "I might as well be set down as a man without any faith at all. I have determined to go forthwith to Vigevano to visit the Signor Marchese, as I have now been here for three days and am weary of the delay, but I promise when I return that I will show you all the rules." Cardan replied: "As you are bent on going to Vigevano, I will give you a letter of introduction to the Marchese, so that he may know who you are; but I would that, before you start, you show me the rule as you have promised." "I am willing to do this," said Tartaglia, "but I must tell you that, in order to be able to recall at any time my system of working, I have expressed it in rhyme; because, without this precaution, I must often have forgotten it. I care naught that my rhymes are clumsy, it has been enough for me that they have served to remind me of my rules. These I will write down with my own hand, so that you may be assured that my discovery is given to you correctly." Then follow Tartaglia's verses: "Quando chel cubo con le cose apresso Se agualia
Paul III. was still in correspondence with the Duke of Urbino, who showed himself not only willing to meet the Pope's wishes with regard to the Tomb of Julius, but also very well disposed toward the sculptor. In July 1537, Hieronimo Staccoli wrote to the Duke of Camerino about a silver salt-cellar which Michelangelo had designed at his request.
This, with the travels of Nicolo le Comte, the Venetian, and of Hieronimo da San Stefano, a Genoese, are said to have been the principal lights by which the Portuguese guided themselves in their voyages. Above all, the influence which the work of Marco Polo had over the mind of Columbus, gives it particular interest and importance. It was evidently an oracular work with him.
Here he erected a very high cross, on which was carved a statement to the effect that he had reached this spot, so that if Coronado's men should find it, they would know he had ascended the river thus far. Town of San Hieronimo is Established.
Lawrence and that of Sumatra," the other is a map of the world, bearing the name of Hieronimo de Verrazzano.
The letter of Carli, enclosing that of Verrazzano, is professedly written by a Florentine to his father in that city. The map of Hieronimo de Verrazano bears the impress of the family. The discourse of the French captain of Dieppe appears to have been sent originally to Florence, whence it was procured by Ramusio.
K. states, however, that he had not seen the map of Hieronimo de Verrazano, and evidently derives his information, in regard to the sea of Verrazano, from the map of Lok, who alone gives the western sea the name of Mare de Verrazana, no doubt because he found the sea laid down on the map presented by Verrazzano to Henry VIII, to which reference will presently be made.
