Rudimentary Architecture – W.H. Leeds – Gece Kitaplığı

In its architectural meaning, the term Order refers to the system of columniation practised by the Greeks and Romans, and is employed to denote the columns and entablature together; in other words, both the upright supporting pillars and the horizontal beams and roof, or trabeation, supported by them. These two divisions, combined, constitute an Order; and so far all Orders are alike, and might accordingly be reduced to a single one, although, for greater convenience, they are divided into three leading classes or families, distinguished as Doric, Ionic, and Corinthian.
