Ionic order edifices antiques de Rome" (Paris 1682). Ionic order The Ionic order forms one of the three classical orders of classical architecture, the other two canonic orders being the Doric and the Corinthian. There are two lesser orders: the Tuscan (a plainer Doric), and the rich variant of Corinthian called the composite order, both added by 16th-century Italian architectural writers, based on Roman practice. Of the three canonic orders, the Ionic order has the narrowest columns. The Ionic capital is characterized by the use of volutes. The Ionic columns normally stand on a base which separates the shaft of the column
Tuscan order the vernacular Georgian style that lingered in places like New England and Ohio deep into the 19th century. In gardening, "carpenter's Doric" which is Tuscan, provides simple elegance to gate posts and fences in many traditional garden contexts. Tuscan order The Tuscan order is in effect a simplified Doric order, with un-fluted columns and a simpler entablature with no triglyphs or guttae. While relatively simple columns with round capitals had been part of the vernacular architecture of Italy and much of Europe since at least Etruscan architecture, the Romans did not consider this style to be a distinct architectural order
