The document discusses the history and periods of Renaissance architecture from the 15th to 17th centuries. It began as a revival of classical Greco-Roman architectural styles and progressed through three periods - the early Renaissance focused on proportion and geometry; the high Renaissance saw grandeur and harmony; and mannerism brought more experimentation with forms and complex details. Key developments included the emergence of secular palaces over religious buildings and the influence of classical orders like Corinthian columns.
