Leon Battista Alberti

In this course

Alberti appears in the course readings primarily as a foundational figure in cryptography and Renaissance information theory, representing the moment when systematic methods for encoding and decoding information emerged in European thought. His polymathic approach—bridging architecture, art, philosophy, and cryptography—models the kind of cross-disciplinary thinking that the course frames as essential to understanding how machines began to mediate human knowledge and communication. Though the provided excerpts don't directly cite him, Alberti's cryptographic innovations exemplify the Renaissance shift toward algorithmic thinking about hidden messages and systematic transformation of data, a precursor to modern computation and artificial intelligence's underlying logics.

Background

Leon Battista Alberti was an Italian Renaissance humanist author, artist, architect, poet, priest, linguist, philosopher, and cryptographer; he epitomised the nature of those identified now as polymaths. He is considered the founder of European cryptography, a claim he shares with Johannes Trithemius.
