1. THE place where the temple is to be built having been divided on its length into six parts, deduct one and let the rest be given to its width. Then let the length be divided into two equal parts, of which let the inner be reserved as space for the

2. Next let the width be divided into ten parts. Of these, let three on the right and three on the left be given to the smaller

3. The height of their bases should be one half of that thickness. The plinth of their bases should be circular, and in height one half the height of the bases, the torus above it and congĂ© being of the same height as the plinth. The height of the capital is one half the thickness of a column. The abacus has a width equivalent to the thickness of the bottom of a column. Let the height of the capital be divided into three parts, and give one to the plinth (that is, the abacus), the second to the echinus, and the third to the necking with its congĂ©.

4. Upon the columns lay the main beams, fastened together, to a height commensurate with the requirements of the size of the building. These beams fastened together should be laid so as to be equivalent in thickness to the necking at the top of a column, and should be fastened together by means of dowels and dove-tailed tenons in such a way that there shall be a space two fingers broad between them at the fastening. For if they touch one another, and so do not leave airholes and admit draughts of air to blow between them, they get heated and soon begin to rot.

5. Above the beams and walls let the mutules project to a distance equal to one quarter of the height of a column; along the front of them nail casings; above, build the tympanum of the pediment either in masonry or in wood. The pediment with its ridgepole, principal rafters, and purlines are to be built in such a way that the eaves shall be equivalent to one third of the completed roof.

CHAPTER VIII: CIRCULAR TEMPLES AND OTHER VARIETIES

1. THERE are also circular temples, some of which are constructed in monopteral form, surrounded by columns but without
