Head of a man endowed, according to Lavater, with the capacity for profound thought. Drawing, c. 1792.

Lavater compares this physiognomy with the face of Mars engraved on a previous page. One only has to compare the hair (neat and flowing on the thinker, tousled and uncouthly bearded on Mars) to perceive the differences of character

Appears in the book in a chapter called "Of the strength and weakness of constitution"

[London], 1792?
