Explore the Production about the History of the mosaic of this artwork.
The mosaic is made of about one and a half million tiny colored tiles called tesserae, arranged in gradual curves called opus vermiculatum (also known as "worm work", because they seem to replicate the slow motion of a crawling worm) rather than opus signinum or other forms of stone chips put in mortar.  These tesserae were about 0.08 inches (0.20 cm) wide, and it is estimated that over four million pieces were used in the mosaic.The color scale of Roman mosaics are extremely rich in gradation. The process of gathering materials for mosaics was a complex undertaking since the color scale was based solely on the pieces of marble that could be found in nature. Following the style of many other Hellenistic artists, the entire mosaic is composed of reds, yellows, black, and white. The mosaic is an unusually detailed work for a private residence and was likely commissioned by a wealthy person or family. There is evidence that the mosaic was imported from the East, as there are places where some details are distorted and changed. Some scholars argue that this is evidence that the mosaic was created in pieces and reassembled in Pompeii.The fact that this scene was made to be viewed in the house of a Roman civilian reveals that Alexander the Great was more than just a heroic image to the Romans. Because Roman leaders followed after Alexander's image, Roman civilians also aspired to emulate the power he represented. Since the mosaic was arranged on the floor where the patron could receive guests, it was the first decorative object a visitor would see upon entering that room. Modern research indicates that there may have been multiple columns removed from the colonnade to improve lighting and viewing of the mosaic.Similar to Greek paintings, the mosaic of Alexander the Great lacks rich iconography towards the top, which, on a vertical surface, would have been considerably higher above the viewer's line of sight and garnered less creative attention. This is one way in which the two forms of art are comparable to one another. As a bonus, the mosaic displays the realism and naturalism typical of Greek portrayals of humans, especially regarding facial expression, emotional tone, and anatomical structure.
