Doric order The Roman architect Vitruvius, following contemporary practice, outlined in his treatise the procedure for laying out constructions based on a module, which he took to be one half a column's diameter, taken at the base. An illustration of Andrea Palladio's Doric order, as it was laid out, with modules identified, by Isaac Ware, in "The Four Books of Palladio's Architecture" (London, 1738) is illustrated at Vitruvian module. According to Vitruvius the height of Doric columns is six or seven times the diameter at the base. This gives the Doric columns a shorter, thicker look than Ionic columns, which have 8:1

All of these details suggest an Alexandrian workshop, since Alexandria showed the greatest tendency to combine Doric entablatures with Corinthian capitals and to do without the plinth under Attic bases. A further plan option is shown by the temple of Hekate at Lagina, a small "pseudoperipteros" of 8 × 11 columns. Its architectural members are entirely in keeping with the Asian/Ionic canon. Its distinctive feature, a rich figural frieze, makes this building, erected around 100 BC, an architectural gem. Further late
