Italy. Pompeii Tile Mosaic, 1/2 inch tiles; National Museum of Archeology, Naples

The Naples National Museum mosaic collection “comprises portions of floor decorations and some wall decorations dating from the two centuries before Christ and up to 79 A.D., almost all of them from Pompei, Herculaneum and Stabiae. The majority are emblèmata, scenes with figures often derived from Greek paintings. On display are two scenes from the “new style comedy”, signed by Dioskourides of Samos, and the rich array of mosaics from the House of the Faun in Pompei, which includes the famous scene from a battle between Alexander the Great and the Persians under Darius. Also of particular interest are the three sectilia, rare examples of this technique of inlaying different coloured marbles in a slate base to depict figures.”
