[Illustration: FIG. 56.--THE ROOF OF A GREEK DORIC TEMPLE, SHOWING THE MARBLE TILES.] The construction of this temple was of the most solid and durable kind, marble being the material used; and the workmanship was most careful in every part of which remains have come down to us. The roof was, no doubt, made of timber and covered with marble tiles (Fig. 56), carried on a timber framework, all traces of which have entirely perished; and the mode in which it was constructed is a subject upon which authorities differ, especially as to what provision was made for the admission of light. The internal columns, found in other temples as well as in the Parthenon, were no doubt employed to support this roof, as is shown in Bötticher's restoration of the Temple at Pæstum which we reproduce (Fig. 56a), though without pledging ourselves to its accuracy; for, indeed, it seems probable that something more or less like the clerestory of a Gothic church must have been employed to admit light to these buildings, as we know was the case in the Hypostyle Hall at Karnak. But this structure, if it existed, has entirely disappeared.[12] [Illustration: FIG. 56a.--SECTION OF THE GREEK DORIC TEMPLE AT PÆSTUM. AS RESTORED BY BÖTTICHER.] [Illustration: FIG. 57.--THE GREEK DORIC ORDER FROM THE THESEUM.] The order of the Parthenon was Doric, and the leading proportions were as follows:--The column was 5·56 diameters high; the whole height, including the stylobate or steps, might be divided into nine parts, of which two go to the stylobate, six to the column, and one to the entablature.
