Conclavibus autem, ubi ignis aut plura lumina sunt ponenda, pura fieri debent, ut ea facilius extergeantur; in aestivis et exhedris, ubi minime fumus est nec fuligo potest nocere, ibi caelatae sunt faciendae.
In apartments, however, where there is a fire and lamps, the cornices should be plain so that they may be the more easily dusted. They can be carved in summer rooms and exedrae where there is very little smoke and soot cannot do any damage.
