'A view of the Colonacce. This giant pair of Corinthian columns in purple and white marble, and the associated frieze of Minerva teaching the arts of sewing and weaving, were part of the colonnade on the northeast side of the Temple of Minerva in the Forum of Nerva. They are all that remains of the ancient Roman temple which was pulled down in the 17th century by Pope Paul V to provide marble for the fountain of the Acqua Paola he was erecting on the Janiculum.'
