In the context of this artwork, discuss the Originality of the History of the mosaic.
The Alexander Mosaic is believed to be a copy of a Hellenistic Greek painting made during the 4th century BC.  The style of the mosaic is distinctly Greek in that it depicts close up portraits of the main heroes of the battle. Typically within Greek battle scenes the heroes are difficult to define within the commotion. The mosaic contains very specific details that scholars believe would have been lost if the mosaic was created any later than a couple hundred years after the battle. It is a commonly accepted belief concerning the Alexander mosaic that one must use the Greek original to interpret the meaning of the Roman copy. The debate among scholars over the significance of the Roman copy is that it cannot and should not be interpreted in the same cultural and historical context as the Greek original. Some believe that in doing so, it takes away both context and achievement from Roman artists. The mosaic is held to be a copy either of a painting by Aristides of Thebes, or of a lost late 4th-century BC fresco by the painter Philoxenus of Eretria. The latter is mentioned by Pliny the Elder (XXXV, 110) as a commission for the Macedonian king Cassander.
