We
are making here the really minimum Greek temple, a Greek temple boiled
down to essentials. I have shown, therefore, a temple with only twelve
columns. You could, if you wished, make yours larger. However, I think
it wise for a beginner to stick exactly to the illustrations.
Choose, now, twelve nice, even, square pieces of stone (or marble if you prefer), and place them evenly around the plinth, being careful to line them up precisely, so the edges are parallel to the edges of the plinth. Use a ruler to get them an even distance from the edges of the plinth.
