Medici Money: Banking, metaphysics and art in fifteenth-century Florence

Lorenzo was to be known as Il Magnifico. So much for keeping out of the public eye. Just twenty when thrust into the limelight, he puts his eggs in other baskets than finance and commerce, allowing the family bank to slide into now-irretrievable decline. Like his father and grandfather, Lorenzo survives a major conspiracy and shows great skills of political manipulation. Unlike them, he aspires to the aristocracy, writes poetry (good poetry), and barely seeks to disguise a vocation for dictatorship. In 1492, aged forty-three, unable, due to the gout, to visit his portly mistress, Lorenzo finally succumbs to a variety of ailments.

Last of the five, Piero di Lorenzo would all too soon be known as Piero the Fatuous. His father’s artistic achievements and pretensions to nobility proved less transferable as assets than the vast monetary wealth left by his great-grandfather, now drastically diminished. Born in 1472, Piero possessed but one talent, a flair for the game of Florentine football, as a result of which his two years as head of the family were an unhappy parody of his father’s more effective maneuverings. He fled Florence, perhaps unnecessarily, as French troops approached the city in 1494. The family wealth was confiscated, the bank collapsed, and ten years later Piero confirmed his incompetence, or perhaps just bad luck, when he drowned crossing the Garigliano, a river north of Naples.

The trajectory, then, is clear enough. One hundred years. Five generations. A vertiginous rise of fortune — first economic, then political — in the hands of two most able administrators. A brief hinge period presided over by a grumpy, middle-aged man in bed. Then two and a half decades of political ascendancy predicated on a wealth that is rapidly disappearing. Followed by sudden and complete collapse. To which we might add that despite their different characters, our five Medici have certain traits in common beyond the gout. They were all ugly, Il Magnifico spectacularly so. And they were avid collectors: of sacred relics and ceremonial armor, of manuscripts, of jewels, of cameos. The collecting habit, with its impulse toward control, order, and possession, is akin to the spheres of both banking and art.

WHEN WE THINK of the period that has come to be known as the Renaissance, we think above all of the fifteenth and early sixteenth centuries; we think of the great art and architecture produced then, from Brunelleschi to Michelangelo; and we are aware of the Medici insofar as they had a relation to that art and those artists. Hence we think of them, and above all of Cosimo and Lorenzo, as living in the heyday of early modern times, before which, with the forward-looking exceptions of Dante, Giotto, and Boccaccio, all is darkness. Thus the myth. Yet there is a sense in which the men we are talking about, and particularly Giovanni di Bicci and Cosimo, must have seen themselves rather as coming afterward, of living in the aftermath of something, not the beginning of a golden age.

As bankers they came after the innovations that had given the Italians a virtual monopoly on European finance: after the invention of double-entry bookkeeping, after the advent of the bill of exchange, the letter of credit, and the deposit account. The Medici invented nothing in banking practice, unless perhaps we are to think of the relation between their parent company and subsidiaries as an early form of holding. What’s more, all the Medici would have been very aware of coming after banks far larger than their own. The Bardi and Peruzzi banks of the thirteenth and fourteenth centuries had amassed fortunes that the Medici would never equal. Both collapsed in the 1340s, when Edward III of England reneged on huge debts. Giovanni di Bicci de’ Medici was in partnership with various men of the Bardi family, employed others, and married his son Cosimo to a Bardi girl. Memories of past glory and a sense of the precariousness of banking wealth must often have been on his mind.

Then, as citizens of Florence, the Medici came after all the upheavals that had made their republic what it was: after the slow collapse of feudal law as the Holy Roman Empire turned its attention northward and lost its grip on a rapidly fragmenting Italy; after the transfer of power, amid endless upheavals, from hereditary lords based in the country to the wealthy classes of the cities; after the formation of a Florentine state with a republican constitution; after the war against papal Rome when the city’s government seized and sold Church property until the people rebelled in a frenzy of religious feeling that eventually turned political in the revolt of 1378. This was the so-called ribellione dei ciompi, when the city’s poor woolworkers tried to oust the mercantile classes as they, the merchants, had ousted the nobles a century before.
