The proximity of the gods was signaled by a particular odor, called the ‘sweat of God.’ The hieroglyph for ‘joy’ is a nose.
~ Rose-Marie and Rainer Hagen, Masterpieces in Detail
One wonders if the odor in question was commonly met with and recognized by all (which would make the gods’ presence pervasive, if invisible), or if it was occult knowledge, passed by oath and threat from one generation of priests to another. For all we know, an Egyptian subdeacon milling about Saqqara nose-drunk on incense and roast ibis might recognize the divine perspiration in our modern combo of diesel fumes and fried chicken. But our godforsaken era lives in ignorance.
