The Affecter was an Attic black-figure vase painter, active in Athens around 550 to 530 BCE.
His conventional name is derived from his artificial affected style of figural painting, on the basis of which about 135 vases can be ascribed to him. He was active as both potter and painter. His speciality was amphorae. He mainly painted ovoid amphorae and belly amphorae, of the then newly introduced type C. Most of the 132 vases associated with him were found in Etruscan tombs and as such are usually well preserved.
He was interested particularly in the decorative effect of his images, composed of stylised figures in long cloaks or with affected gestures; narrative content was secondary. In his tendency to formulaic figures and multiple details, the Affecter is a successor to the Amasis Painter, from whom he may have learnt his trade. Together with the painter Elbows Out, he is considered to be a mannerist of the black-figure style.
His images often seem to reflect a surreal world. His figures usually have small heads and seemingly upholstered bodies, when clothed, or angular pointed ones, when naked. His ornaments are very carefully drawn.
