UPPER LIP BOW AND PHILTRUM ARE KEY DEVELOPMENTAL MARKERS

(details from "Portrait of a Man") (see related A | B | C), 1507 Hans Schauffelein (1480-1538) National Gallery of Art , Washington, DC, USA

Relatively thin upper lip mucosa or vermilion and above its "Cupids" bow, a rather deep and wide "philtrum", a site where the ancients smeared with "per- fume" or perfumes to "filter" out the odor or odors pervasive along ancient streets (sewage often flowed in open street gutters). A flat bow and/or philtrum may be a signal of prenatal mal-development - and if so may indicate alcohol as a cause (etiology). However the presence of philtrum strongly argues that this person was not prenatally exposed to alcohol.
