The Forge of Vulcan is a oil painting by the Spanish painter Diego Velazquez. The pictures Velázquez produced in Italy include the large Forge of Vulcan. The god of fire and his assistants are working a red-hot piece of metal in the forge, which is grey with dust, and another journeyman is making a suit of knightly armour, its materiality depicted with a masterly touch. This painting (223 x 290 cm) is currently housed in the Museo del Prado, Madrid.
