amphoras. Two hydria attributed to him are decorated on the neck region using a white ground technique. He was the first to paint amphoras with a masklike face of Dionysus. The most famous of his over 200 surviving vases shows an olive harvest on the back side. His drawings are seldom really precise, but neither are they excessively careless. Stylistically, the painter Psiax is closely related to the Antimenes Painter, although the former also used the red-figure technique. As the teacher of the painters Euphronius and Phintias, Psiax had a great influence on the early development of the red-figure style. He frequently shows horse and chariot scenes and archers. The last important group of painters was the Leagros Group (520-500 BC), named after the kalos inscription they frequently used, Leagros. Amphoras and hydria, the latter often with palmettes in the predella, are the most frequently painted vessels. The image field is usually filled absolutely to capacity, but the quality of the images is still kept very high. Many of the over 200 vases in this group were decorated with scenes of the Trojan War and the life of Heracles Painters like the witty Acheloos Painter, the conventional Chiusi Painter, and the Daybreak Painter with his faithful detailing belong to the Leagros Group. Other well-known vase painters of the time are the Painter of the Vatican Mourner, The Princeton Painter, the Painter of Munich 1410 and the Swing Painter (540-520 BC), to whom many vases are attributed. He is not considered to be a very good artist, but his figures are unintentionally humorous because of the figures with their large heads, strange noses and frequently clenched fists. The work of the Rycroft Painter bears a resemblance to red-figure vase painting and the new forms of expression. He liked to depict Dionysian scenes, horses and chariots, and the adventures of Heracles. He often uses outline drawings. The approximately 50 usually large-size vessels attributed to him are elegantly painted. The Class of C.M. 218 primarily decorated variations of the Nikosthenic amphoras. The Hypobibazon Class worked with a new type of belly amphora with rounded handles and feet, whose decoration is characterized by a key meander above the image fields. A smaller variant of neck amphora was decorated by the Three Line Group. The Perizoma Group adopted around 520 BC the newly introduced form of the stamnos. Toward the end of the century, high
