The document discusses Leon Battista Alberti, an Italian Renaissance polymath known for his works on architecture, sculpture, painting, and literature. Specifically, it examines some disadvantages or critiques of Alberti's views on ornamentation and decoration in architecture. While Alberti and Vitruvius viewed decoration as something extra or added to the main work, this view is questioned - if beauty is intrinsic, how can decoration that is added be considered part of it? The document also notes that Alberti's definition of beauty prioritized an intrinsic, all-encompassing quality rather than something that can accept additions or subtractions.
