Note 565 — ADDITIONAL NOTES.

“Dipteros autem octastylos et pronao et postico, sed circa ædem duplices habet ordines columnarum sicut est ædes Quirini Dorica, et Ephesiæ Dianæ Ionica a Chersiphrone constituta.” Vitr. l. 3. c. 2.

Such is his definition of the dipterus which he confines to octastyle temples; although we find that all the decastyle temples in existence are dipteral, that is to say, that they have a double range of columns round the cell. In like manner he defines the peripteri as having six columns in front, though all temples with a greater number of columns in front are in fact peripteral, or having a cell surrounded with columns. Thus also he defines the hypæthri as temples having ten columns in front, though we know that the Parthenon and the temple of Delphi, neither of which had so many columns, were hypæthral, or with a part of the cella open to the sky. But, in truth, Vitruvius himself often forgets his own definitions, and uses the Greek terms just mentioned according to their real meaning.
