Leon Battista Alberti

Leon Battista Alberti (born Feb. 14, 1404, Genoa—died April 25, 1472, Rome) was an Italian humanist, architect, and principal initiator of Renaissance art theory. In his personality, works, and breadth of learning, he is considered the prototype of the Renaissance “universal man.”

Childhood and education

The society and class into which Alberti was born endowed him with the intellectual and moral tendencies he was to articulate and develop over a lifetime. He belonged to one of the wealthy merchant-banker families of Florence. At the time of his birth, the Alberti were in exile, expelled from Florence by the oligarchical government then dominated by the Albizzi family. Alberti’s father, Lorenzo, was managing the family’s concerns in Genoa, where Battista was born. Shortly thereafter he moved to Venice, where he raised Battista (Leo or Leon was a name adopted in later life) and his elder brother, Carlo. Both sons were illegitimate, the natural offspring of Lorenzo and a Bolognese widow, but they were to be Lorenzo’s only children and his heirs. An affectionate and responsible father, Lorenzo provided his sons with a Florentine stepmother (whom he married in 1408), and he attended carefully to their education.

It was from his father that Battista received his mathematical training. The useful intellectual tools of the businessman inspired in him a lifelong love for the regular, for rational order, and a lasting delight in the practical application of mathematical principles. “Nothing pleases me so much,” Alberti was to have a figure in one of his dialogues remark, “as mathematical investigations and demonstrations, especially when I can turn them to some useful practice as Battista here did, who drew from mathematics the principles of painting [perspective] and also his amazing propositions on the moving of weights.” As in Leonardo da Vinci’s case, mathematics led Alberti into several seemingly disparate fields of learning and practice. At one stroke, it resolved a diversity of problems and awakened an appreciation of the rational structure and processes of the physical world.

His early formal education was humanistic. At the age of 10 or 11, Alberti was sent to boarding school in Padua. There he was given the classical Latin training that was to be denied to Leonardo, illegitimate son of a poor notary in a rustic village of Tuscany. The “new learning” was largely literary, and Alberti emerged from the school an accomplished Latinist and literary stylist. Relishing his skill as a classicist, he wrote a Latin comedy at the age of 20 that was acclaimed as the “discovered” work of a Roman playwright—and was still published as a Roman work in 1588 by the famous Venetian press of Aldus Manutius. But it was the content rather than the form of the classical authors that absorbed Alberti as a youth and throughout his life. As for most humanists, the literature of ancient Rome opened up for him the vision of an urbane, secular, and rational world that seemed remarkably similar to the emerging life of the Italian cities and met its cultural needs. He brought his own emotional and intellectual tendencies to “the ancients,” but from them he drew the conceptual substance of his thought.

Alberti completed his formal education at the University of Bologna in an apparently joyless study of law. His father’s death and the unexpected seizure of his legacy by certain members of the family brought him grief and impoverishment during his seven-year stay at Bologna, but he persisted in his studies. After receiving his doctorate in canon law in 1428, he chose to accept a “literary” position as a secretary rather than pursue a legal career. By 1432 he was a secretary in the Papal Chancery in Rome (which supported several humanists), and he had a commission from a highly placed ecclesiastical patron to rewrite the traditional lives of the saints and martyrs in elegant “classical” Latin. From this point on, the church was to provide him with his livelihood. He took holy orders, thus receiving in addition to his stipend as a papal secretary an ecclesiastical benefice, the priory of Gangalandi in the diocese of Florence, and some years later Nicholas V conferred upon him as well the rectory of Borgo San Lorenzo in Mugello. Although he led an exemplary, and apparently a celibate, life, there is almost nothing in his subsequent career to remind one of the fact that Alberti was a churchman. His interests and activities were wholly secular and began to issue in an impressive series of humanistic and technical writings.
