Renaissance humanism
North Italian economy
We can measure the economic driver of the Renaissance by comparing the 15th century Venetian economy with other economies of the time. A Venetian document conveniently offers us a list of European budgets in the early fifteenth century. 
Whereas receipts for the city of Venice alone were between 750,000 and 800,000 ducats, the entire kingdom of France (in a parlous state at the time it is true) could assemble a mere million ducats; Venice's budget was equal to that of Spain (though quite what 'Spain' means in this context is disputed), almost equal to that of England, and far exceeded those of the other Italian cities deemed to be her peers: Milan, Florence and Genoa. It is true that the figures for the budget of Genoa do not mean much, since private interest had commandeered a huge slice of public revenue for itself.
And so far, we have only been talking about Venice and the Dogado. To the revenue of the Signoria (750,000 ducats) we should add those of the hinterland, Terraferma (464,000) and of the empire - the Mar or sea as it was called (376,000). The total (1,615,000 ducats) sets the Venetian budget in the front rank of budgets in Europe - and even this is not quite the whole story. For if the population of the entire Venetian complex (city, Terraferma and empire) is estimated at about one and a half million maximum, and that of France under Charles VI as fifteen million (for the purposes of a very rough and ready calculation), then the latter, with ten times as many inhabitants, ought to have had a budget ten times that of Venice - viz. 16 million ducats.
The paltry size of the French budget, one million, serves to underline the overwhelming superiority of the city-states compared to the 'territorial' economies and allows one to imagine what this early concentration of capital must have signified for a single city - when all is said and done a mere handful of men. To suggest a further interesting if not conclusive comparison: the same document reveals that budgets had shrunk in the fifteenth century, but unfortunately without indicating the year in which the decline began. Compared to the former level, the English budget had apparently fallen by 65%, that of Spain (again what 'Spain'?) by 73%, but that of Venice by only 2.7%.
The second test we can apply, defines the beginnings of consumerism.  It is the celebrated speech of the doge Mocenigo, a combination of last will and testament, statistical survey and political invective. On the point of death, the old doge made a desperate attempt to prevent the succession of Francesco Foscari, of the war party (who did in fact succeed him on 14 April 1423, and presided over Venice's destiny until his deposition on 2.3 October 1457). The old doge explained to his listeners the advantages of peace if the fortunes of the state and its citizens were to be preserved.
If you elect Foscari, he said:
'you will soon be at war. The man who has 10,000 ducats now will be left with a thousand, he who has ten houses will have only one, he who has ten garments will hardly have one, those with ten petticoats or pairs of hose or shirts will hardly have one left and so it will be with everything'. If on the contrary, the peace is kept, 'if you follow my advice, you will find that you are the masters of the gold of Christendom'.
The Renaissance
It was the Venetian monopoly of world trade that kick- started the Renaissance and all that paraphernalia of the modern world that stemmed from it.  The economic drivers were merchants  who aspired to control their own destinies and their wealth bought the latest fashions and their patronage of craftsment and artists bought the materials and thinking time for the likes of Giotto and Michelangelo to progress the visual arts..The founder of Renaissance humanism is said to be Petrarch (1304- 74), an Italian poet and man of letters who attempted to apply the values and lessons of antiquity to questions of Christian faith and morals in his own day.
The Renaissance is a milestone in the fifteenth century, a turning point in art and attitudes to art, in learning, in science; a new vision of the individual and his worth; a 'rebirth'; the beginning of a new world. This view is commonplace and hardly to be overturned—it is in fact how men of the late Renaissance, such as Vasari in Italy and Rabelais in France, have themselves advertised what they and their like have been doing; and we have continued to listen to their testimony and still use the very suggestive name they have put into circulation.
Yet we recognize it to have been a tendentious name. It focuses our attention on a particular range of their concerns; it disregards the discovery of a New World (named after a Florentine); it bypasses a European transformation which many would judge of central importance (the Protestant Reformation); it crowds out Copernicus's revolution in astronomy and actually obscures the process by which modern science slowly begins to emerge from ancient beliefs. Its claim for novelty, even, in recovering the ancient world and through it so many occasions for pride, is disproved by history; there is not one Renaissance, there have been numerous earlier occasions on which a cultural 'rebirth' has been sparked off by partial returns to antiquity. The century immediately preceding the great fifteenth century refulgence in Florence is, in particular, an age of 'Renaissance', with Petrarch at the centre of a quickening of attention to ancient Rome; while in the sequel there spreads out from Florence a whole ripple of 'Renaissances' of various degrees of deliberateness, in other lands, lasting well into the 1530s and even beyond. In short, we no longer see the world as Rabelais did.
For all that, the Renaissance, if not an absolute novelty, yet forms part of a set of changes so striking in their outcomes as to warrant our attention, and our retention of the name—if not quite in the sense propagated by its sixteenth-century adherents.  Above all there is a new mental attitude towards understanding the environment.  The world and our place in it was subjected to human analysis by a process of framing, that is to say, deciding where to place the boundaries between clusters of objects and ideas.  This is a fundamental apect of human behaviour which led to the framing of living beings and the physical world as a gallery of interacting and interdependent entities.
