The Latin phrase Ordo Tuscanicus first appeared in the 6th century within Isidore of Seville's Etymologiae. This text grouped a simple columnar style with other classical forms for the first time. Roman architects like Vitruvius did not list this style as a distinct order alongside Doric, Ionic, and Corinthian systems. They described round columns without flutes but never named them Tuscan. Etruscan vernacular architecture across Italy featured these sturdy unfluted columns long before Renaissance theorists cataloged them. The Romans ignored the classification while building temples and public spaces throughout their empire. It remained an informal part of local Italian building traditions until scholars revived it centuries later.
Renaissance Theoretical Development
Sebastiano Serlio published his fourth book Regole generali di architettura sopra le cinque maniere de gli edifici in 1537. He introduced five orders including what he called the solidest and least ornate Tuscan order. Fra Giocondo had illustrated a Tuscan capital in his 1511 printed edition of Vitruvius. That drawing showed egg and dart enrichment which actually belonged to the Ionic order instead. Andrea Palladio carefully delineated the most rustic version of Serlio's design in his own treatises. Vignola published Cinque ordini d'architettura in 1562 with clear illustrations of the system. These printed works defined proportions that earlier builders had only used by habit or local custom. Theorists sought precedents in Vitruvius even though he offered no indication of the column's specific capital shape.Structural Characteristics And Proportions
