73 .-- Section of the hypostyle hall at Karnak to show the arrangement of the two varieties: campaniform and lotus-bud columns.] Shafts of columns were regulated by no fixed rules of proportion or arrangement.

The architect might, if he chose, make use of equal heights with very different diameters, and, regardless of any considerations apart from those of general harmony, might design the various parts according to whatever scale best suited him.

The dimensions of the capital had no invariable connection with those of the shaft, nor was the height of the shaft dependent on the diameter of the column.

At Karnak, the campaniform columns of the hypostyle hall measure 10 feet high in the capital, and 55 feet high in the shaft, with a lower diameter of 11 feet 8 inches.

At Luxor, the capital measures 11-1/2 feet, the shaft 49 feet, and the diameter at the spring of the base 11-1/4 feet.
