Although
Physiognomonics is the earliest work surviving in Greek devoted to the subject, texts preserved on clay tablets provide evidence of physiognomy manuals from the
First Babylonian dynasty, containing divinatory case studies of the ominous significance of various bodily dispositions. At this point physiognomy is "a specific, already theorized, branch of knowledge" and the heir of a long-developed technical tradition. While loosely physiognomic ways of thinking are present in Greek literature as early as
Homer, physiognomy proper is not known before the
classical period. The term
physiognomonia first appears in the fifth-century BC
Hippocratic treatise
Epidemics (II.5.1). Physiognomy was mentioned in a work by
Antisthenes on the
Sophists, which provides evidence of its recognition as an art (
techne). In Aristotle's time, physiognomics was acknowledged as an art (
techne) with its own skilled practitioners (
technitai), as we see from a reference in
Generation of Animals (IV.3): Then people say that the child has the head of a ram or a bull, and so on with other animals, as that a calf has the head of a child or a sheep that of an ox. All these monsters result from the causes stated above, but they are none of the things they are said to be; there is only some similarity, such as may arise even where there is no defect of growth. Hence often jesters compare someone who is not beautiful to a goat breathing fire, or again to a ram butting, and a certain physiognomist reduced all faces to those of two or three animals, and his arguments often prevailed on people. (trans. Pratt rev.
Barnes) Already in antiquity, physiognomy's pretensions to a "scientific" foundation were questioned and debated. It had connections to
medicine, but also to
magic and
divination. ==The treatise==
