Faun at Pompeii (now in Naples). It is believed to be a copy of a painting described by Pliny which had been painted by Philoxenus of Eretria for King Cassander of Macedon at the end of the 4th century BC, or even of a painting by Apelles contemporaneous with Alexander himself. The mosaic allows us to admire the choice of colors along with the composition of the ensemble using turning movement and facial expression. Stag Hunt mosaic The Stag Hunt Mosaic by Gnosis is a mosaic from a wealthy home of the late 4th century BC, the so-called "House of the Abduction of Helen" (or "House of the Rape of Helen"), in Pella, The signature ("Gnosis epoesen", i.e. Gnosis created) is the first known signature of a mosaicist. The emblema is bordered by an intricate floral pattern, which itself is bordered by stylized depictions of waves. The mosaic is a pebble mosaic with stones collected from beaches and riverbanks which were set into cement. As was perhaps often the case, the mosaic does much to reflect styles of painting. The light figures against a darker background may allude to red figure painting. The mosaic also uses shading, known to the Greeks as skiagraphia, in its depictions of the musculature and cloaks of the figures. This along with its use of overlapping figures to create depth renders the image three dimensional. Sosos The Hellenistic period is equally the time of development of the mosaic as such, particularly with the works of Sosos of Pergamon, active in the 2nd century BC and the only mosaic artist cited by Pliny. His taste for trompe-l'œil (optical illusion) and the effects of the medium are found in several works attributed to him such as the "Unswept Floor" in the Vatican museum, representing the leftovers of a repast (fish bones, bones, empty shells, etc.) and the "Dove Basin" (made of small opus vermiculatum tesserae stones) at the Capitoline Museum, known by means of a reproduction discovered in Hadrian's Villa. In it one sees four doves perched on the edge of a gilt bronze basin filled with water. One of them is watering herself while the others seem to be resting, which creates effects of reflections and shadow perfectly studied by the artist. The "Dove Basin" mosaic panel is an emblema, designed to be the central point of an otherwise plain mosaic floor. The emblema was originally
