This statistical view of things was at a later time still more highly cultivated at Florence. The noteworthy point about it is that, as a rule, we can perceive its connection with the higher aspects of history, with art, and with culture in general. An inventory of the year 1422[166] mentions, within the compass of the same document, the seventy-two exchange offices which surrounded the ‘Mercato Nuovo;’ the amount of coined money in circulation (two million golden florins); the then new industry of gold spinning; the silk wares; Filippo Brunellesco, then busy in digging classical architecture from its grave; and Lionardo Aretino, secretary of the republic, at work at the revival of ancient literature and eloquence; lastly, it speaks of the general prosperity of the city, then free from political conflicts, and of the good fortune of Italy, which had rid itself of foreign mercenaries. The Venetian statistics quoted above (p. 70), which date from about the same year, certainly give evidence of larger property and profits and of a more extensive scene of action; Venice had long been mistress of the seas before Florence sent out its first galleys (1422) to Alexandria. But no reader can fail to recognise the higher spirit of the Florentine documents. These and similar lists recur at intervals of ten years, systematically arranged and tabulated, while elsewhere we find at best occasional notices. We can form an approximate estimate of the property and the business of the first Medici; they paid for charities, public buildings, and taxes from 1434 to 1471 no less than 663,755 gold florins, of which more than 400,000 fell on Cosimo alone, and Lorenzo Magnifico was delighted that the money had been so well spent.[167] In 1472 we have again a most important and in its way complete view of the commerce and trades of this city,[168] some of which may be wholly or partly reckoned among the fine arts--such as those which had to do with damasks and gold or silver embroidery, with woodcarving and ‘intarsia,’ with the sculpture of arabesques in marble and sandstone, with portraits in wax, and with jewellery and work in gold. The inborn talent of the Florentines for the systematisation of outward life is shown by their books on agriculture, business, and domestic economy, which are markedly superior to those of other European people in the fifteenth century. It has been rightly decided to publish selections of these works,[169] although no little study will be needed to extract clear and definite results from them. At all events, we have no difficulty in recognising the city, where dying parents begged the Government in their wills to fine their sons 1,000 florins if they declined to practise a regular profession.[170]
