What happened
Around 1416, the architect Filippo Brunelleschi had demonstrated in Florence that a painted scene could be constructed so that parallel lines appear to converge on a single vanishing point, matching how the eye actually perceives depth, but he left no written account of the method. In 1435, the humanist and architect Leon Battista Alberti wrote that method down in his treatise De Pictura (On Painting), giving painters a geometric procedure for placing a vanishing point at eye level and building a credible illusion of three-dimensional space on a flat panel. The book had no printing press to spread it yet, since none existed in Florence in 1435, but it circulated in manuscript among Florentine painters and was translated into Italian the following year.
Why it matters
Alberti's treatise turned Brunelleschi's demonstration into a rule other artists could learn and apply, and linear perspective spread from Florence to workshops across Italy over the following decades. It became one of the defining technical tools of Renaissance painting, used by Masaccio, Piero della Francesca, Leonardo, and Raphael to build convincing pictorial space.
How we know
Alberti's Latin text of De Pictura survives in multiple manuscript copies, and both the World History Encyclopedia's entry on Alberti and the Linda Hall Library's scientist-of-the-day essay describe its 1435 date and content from that textual record.
