A collection of studies of heads: A woman in profile to the left, possibly Emma Hamilton; Head of a warrior looking up to the right; Portrait of a man with long hair, in profile to the right; Portrait of an Nicolo Sale, in profile to the left; Portrait of a man with an elaborate queue wearing a high stock, in profile to the right; Plato, bust-length, after the antique; Head of a girl looking down, full face; A youth, bust-length, looking up; and Head of a goddess, after the antique

(1) The portrait of Emma Hamilton is related to Tischbein's portrait of Emma Hamilton as a Sibyl painted in Naples in 1788, and now in the collection of the Nationale Forschungs- und Gedenkstätten, Weimar (Mildenberger, 1986, no. 242).
(3) Another version of the portrait of Nicolo Sale is in the Landesmuseum, Oldenburg (Mildenberger, 1986, no. 240). That portrait bears an inscription identifying the sitter as 'Maestro di Capella Napolitiana', and like the present drawing may date from Tischbein's stay in Naples. The portrait was recorded in an engraving by Tischbein in reverse to the present drawing (Andresen 5), of which there is an example at Oldenburg (Mildenberger, 1986, no. 241). A version of the portrait is included among Tischbein's physiognomical studies in the Goethe Collection at Weimar (M. Oppel, 1991, no. 50). The portrait was reused for Tischbein's illustration of the Schwachmatikus (Ignoramus), the hero of his Eselsgeschichte fable of 1813 (Mildenberger, 1986, no. 102).
