The Metropolitan Museum's famous bronze horse which was declared to be a fraud in 1967, has been declared an irrefutably genuine work of antiquity after a thorough technical examination, which included thermoluminescence, radiography, testing with solvents, and examination of the core material. The misleading sandcastine seams were removed by solvents; they were apparently caused by reproduction casts made of the horse. The metal was analyzed and found to be a copper-tin alloy with low concentrations of lead, zinc, and other metallic trace impurities. Thermoluminescenct dating of the core material was said to provide definitive evidence that the horse was made in ancient times. Thermoluminescence is explained in some detail. The reasoning behind the decisions and stylistic features are also discussed. A radiograph of the horse in question and three other black and white photographs are reproduced. -- AATA
