By the late 18th century many more Europeans were visiting Athens, and the picturesque ruins of the Parthenon were much drawn and painted, helping to arouse sympathy in Britain and France for Greek independence. In 1801 the British ambassador at Constantinople, the Earl of Elgin, obtained a permit from the Sultan to make casts and drawings of the antiquities on the Acropolis, to demolish recent buildings if this was necessary to view the antiquities, and to remove sculptures from them. He took this as permission to collect all the sculptures he could find. Some he prised from the building itself, others he collected from the ground, still others he bought from local people.
