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

Cosimo has Giovanni Benci beside him now as general director of the Medici holding. They work together among the tapestries and sculptures of Cosimo’s house. Benci had made quite extraordinary profits in Geneva. He is astute and gifted and devout. Pondering the accounts together by the light of an open window, do the two men occasionally exchange a snigger over the slave girls, the days in Rome? Are they in agreement with the general Florentine complaint that it’s getting hard to distinguish an honest girl from a prostitute? Do they discuss their contributions to religious institutions, exchange the names of favorite artists — Donatello, Lippi — discuss the latest translations of Cicero, the seductive ideas of the humanists? Why aren’t the Florentine whores happy to wear bells on their heads? Why can’t the Western and Eastern churches agree about the nature of the Trinity? Does the preacher Bernardino di Siena really believe, as he has been claiming in his sermons, that Jews take delight in pissing in consecrated communion cups? Cosimo is now an important figure in the religious confraternity dedicated to the Magi. Contessina fusses over what cloaks he should wear when he rides down the city streets to reenact the three kings’ adoration of the Holy Child.

Together, Giovanni Benci and Cosimo open a Medici branch in Ancona in 1436. This Adriatic port was important for exporting cloth to the East and importing grain from Puglia, farther down the coast. But could that justify the huge capital investment of around 13,000 florins, far larger than the Medici investment in the more important commercial centers of Venice and Bruges? Florence was at war. Once again the Italian scenario was fantastically complicated: a succession dispute down in Naples between the Angevin and Aragon families; the two condottieri, Francesco Sforza and Niccolò Piccinino, at each other’s throats in the Papal States; the pope marooned in Florence, afraid of going back to Rome, worried about developments in Basle, casting about for allies; Duke Filippo Visconti in Milan, with Piccinino in his pay, seeking to capitalize on the turmoil in every area, sending expeditions to Genoa, Bologna, Naples. And now Rinaldo degli Albizzi has left his place of exile and is begging Visconti to attack Florence and restore his family’s faction to power. Undaunted, the incorrigible Florentines are once again launching an assault on Lucca and calling on the Venetians to help them out when it comes to the crunch with Milan. We would, if the Mantuans hadn’t switched sides, the Venetians reply. In the midst of this confusion, Cosimo made a long-term decision to back the great soldier Sforza. The money down in Ancona was not to finance trade at all. Or not exclusively. Ancona was in Sforza’s sphere of operation. It was the Medici bank’s first serious move into funding military operations that were not specifically to do with Florence. Why?

In Milan, the fat, mad, aging Visconti had no legitimate off-spring, just one bastard daughter, Bianca. Sforza wanted her for his wife, together with the Milanese dukedom. He wouldn’t fight against Visconti while that marriage was in the cards. Or not north of the Po, in Visconti’s sphere of influence (he later changed his mind). At the same time, the combination Sforza — Visconti, should the condottiere fight with the duke, was the one feasible alliance capable of inflicting decisive military defeat on Florence. The duke had tied Sforza’s hands with the tease of his daughter, constantly promising that the marriage was about to take place, then inventing reasons for delay. Cosimo responded by tying the condottiere with his cash. Sforza could hardly fight for Visconti and the Albizzi if his army was fed and clothed by the Medici.

The Ancona adventure, though short-lived, marked a turning point in the history of the bank. It fused its destiny with that of the Florentine state. Here was a branch that lent mainly for political purposes, without expecting to recover its capital. Not good news for the small investor. Matters of state go beyond the rationale of any commercial venture. Thirty years later, Sforza would owe the Medici bank something in the region of 190,000 florins, a sum far beyond repayment. This was how the Bardi and Peruzzi banks had gone under years ago. But in 1440, Piccinino, Milan, and the Albizzi faction were decisively beaten by the Florentines at Anghiari, to the south east of the city. Sforza, the most successful military adventurer of the fifteenth century, was up north fighting in the Veneto. He never attacked Florence, despite the fact that the Florentines were his future father-in-law’s bitterest enemies.
