2Spring and autumn triclinia should be towards the east, for then, if the windows be closed till the sun has passed the meridian, they are cool at the time they are wanted for use. Summer triclinia should be towards the north, because that aspect, unlike others, is not heated during the summer solstice, but, on account of being turned away from the course of the sun, is always cool, and affords health and refreshment. Pinacothecæ should have the same aspect, as well as rooms for embroidering and painting, that the colours used therein, by the equability of the light, may preserve their brilliancy.
2Dining rooms for Spring and Autumn to the east; for when the windows face that quarter, the sun, as he goes on his career from over against them to the west, leaves such rooms at the proper temperature at the time when it is customary to use them. Summer dining rooms to the north, because that quarter is not, like the others, burning with heat during the solstice, for the reason that it is unexposed to the sun’s course, and hence it always keeps cool, and makes the use of the rooms both healthy and agreeable. Similarly with picture galleries, embroiderers’ work rooms, and painters’ studios, in order that the fixed light may permit the colours used in their work to last with qualities unchanged.
