Perhaps the most interesting of the particulars relating to library matters imparted by my author are those respecting a man second only to Grolier as a patron of fine binding, but of whose personal character and habits, were it not for Nicius, we should know nothing. Every one interested in the bibliopegic art is more or less acquainted with the beautiful bindings executed for Demetrius Canevarius, physician to Urban VII., elected Pope in 1590, but whom all his leech's skill could not keep alive upon the Papal throne for more than twelve days. This certainly does not seem to have been the fault of the physician, who was, Nicius tells us, a Genoese of noble family, who condescended to the medical profession in the hope of becoming rich. In this there is nothing to criticise; but unfortunately, avarice seems to have been his master passion, indeed his only passion, except the love of books, which has given him an honourable place in literary history. Having removed from Genoa to Rome, he soon obtained the confidence of many of the Cardinals, and became the most celebrated and opulent physician of his day. But his habits were most parsimonious; he never, in his own house, says Nicius, tasted fowl or fish, or anything that any sumptuary law could have forbidden in any age. He lived by himself; his meals, consisting of bread, soup, and a scrap of meat, were brought him by an old woman who never entered the house, and drawn up to the first floor in a basket. He bought his new clothes ready made, and his second-hand clothes from the Jews. As soon as he got any money, he put it out to interest, and when he got the interest upon that, he put it out again. The one exception to this parsimony was the expense to which he went in buying books. Dry as pumice, says Nicius, in every other respect, in this he was most liberal; if you look, that is, to the total sum he expended, and not to the prices he gave for individual books. For he beat the booksellers down unrelentingly, and would carry off their books at much lower prices than they asked, notwithstanding their lamentations and complaints that they were going to be ruined. How could he achieve this? By the magic of ready money; the bibliopole found it better after all to part with the book at a small profit for money down than to keep it on his shelves till some one bought it and forgot to pay. Thus was Canevarius unknowingly a forerunner of the political economists, and an initiator of the principle of small profits and quick returns. Of the bindings which constitute his glory with posterity Nicius says nothing; but ascribes his prowess as a collector in great measure to a love of fame. No unworthy motive either, but it is likely that public spirit had quite as much to do with it; for Canevarius not merely collected the library which he expected to perpetuate his name with posterity, but bequeathed it to his native city of Genoa, and left by his will an annuity of two hundred crowns to a caretaker.
