430 MERGE TO GYRENE.

however, to ascertain that the portico was hexastyle, and the columns about four feet and a half in diameter : those on the south side are so completely buried that no traces of them whatever are visible ; but from those which are still in their places on the opposite side we were led to suppose that the number of columns was no more than ten, instead of eleven, which is the usual proportion in peripteral temples according to the rules laid down by Vitruvius *. As the number of lateral intercolumniations would not, with this disposition, be double the number of those in the front, the whole length of the temple in question could not be equal to twice its breadth, which we accordingly find to be the case : and it is probable, therefore, that the sedes, or body of the temple, was built before the other parts of it, and that the columns and porticoes were added at a subsequent period, and the number of pillars regulated by the dimensions of what was already constructed. At the same time the width of the intercolumniations does not appear to have been greater than seven feet, which is scarcely more (as compared with the size of the shaft) than the shortest space allowed between columns in Greek and Koman architecture f. There are no columns, at either end.

* There are, however, many exceptions to this rule, which does not appear to have been by any means generally adopted by the Gi-eeks. The number of columns on the flanks of temples seem to have been usually (at the same time) more than double the number in front, and seldom less by more than one, the proportion given by Vitruvius.

t The jjycnostyle is the least intercolumniation allowed by Vitruvius, and is one diameter and a half of the column at the bottom of the shaft ; but neither this proportion, nor that of the systyle, which is equal to two diameters of the column, are recommended by him for general adoption: since “the matrons (he adds) who go to their supplications, mutually supporting each other, cannot pass through the intercolumniations
