Michel de Montaigne

“ But the ordinary constitution of human bodies is quite otherwise,
and their best and chiefest excellency is to be exempt from smell. Nay,
the sweetness even of the purest breath has nothing in it of greater
perfection than to be without any offensive smell, like those of
healthful children, which made Plautus say of a woman:
"Mulier tum bene olet, ubi nihil olet." ”

“ Physicians might, I believe, extract greater utility from odours than
they do, for I have often observed that they cause an alteration in me
and work upon my spirits according to their several virtues; which makes
me approve of what is said, that the use of incense and perfumes in
churches, so ancient and so universally received in all nations and
religions, was intended to cheer us, and to rouse and purify the senses,
the better to fit us for contemplation. ”
