And there was infused in that brain such grace from God, and a power of expression in such sublime accord with the intellect and memory that served it, and he knew so well how to express his conceptions by draughtsmanship, that he vanquished with his discourse, and confuted with his reasoning, every valiant wit. And he was continually making models and designs to show men how to remove mountains with ease, and how to bore them in order to pass from one level to another; and by means of levers, windlasses, and screws, he showed the way to raise and draw great weights, together with methods for emptying harbours, and pumps for removing water from low places, things which his brain never ceased from devising; and of these ideas and labours many drawings may be seen, scattered abroad among our craftsmen; and I myself have seen not a few. He even went so far as to waste his time in drawing knots of cords, made according to an order, that from one end all the rest might follow till the other, so as to fill a round; and one of these is to be seen in stamp, most difficult and beautiful, and in the middle of it are these words, "Leonardus Vinci Accademia." And among these models and designs, there was one by which he often demonstrated to many ingenious citizens, who were then governing Florence, how he proposed to raise the Temple of S. Giovanni in Florence, and place steps under it, without damaging the building; and with such strong reasons did he urge this, that it appeared possible, although each man, after he had departed, would recognize for himself the impossibility of so vast an undertaking. He was so pleasing in conversation, that he attracted to himself the hearts of men. And although he possessed, one might say, nothing, and worked little, he always kept servants and horses, in which latter he took much delight, and particularly in all other animals, which he managed with the greatest love and patience; and this he showed when often passing by the places where birds were sold, for, taking them with his own hand out of their cages, and having paid to those who sold them the price that was asked, he let them fly away into the air, restoring to them their lost liberty. For which reason nature was pleased so to favour him, that, wherever he turned his thought, brain, and mind, he displayed such divine power in his works, that, in giving them their perfection, no one was ever his peer in readiness, vivacity, excellence, beauty, and grace.
