Editing Renaissance architecture (section)

=== Columns and pilasters ===
Roman and Greek orders of columns are used: [[Tuscan order|Tuscan]], [[Doric order|Doric]], [[Ionic order|Ionic]], [[Corinthian order|Corinthian]] and [[Composite order|Composite]]. The orders can either be structural, supporting an arcade or architrave, or purely decorative, set against a wall in the form of pilasters. During the Renaissance, architects aimed to use columns, [[pilaster]]s, and [[entablatures]] as an integrated system. One of the first buildings to use pilasters as an integrated system was in the [[Sagrestia Vecchia|Old Sacristy]] (1421–1440) by Brunelleschi.
