Charles-Louis Clerisseau. Charles-Louis Clérisseau was a French architectural draughtsman, antiquary and artist.
He had a role in the genesis of neoclassical architecture during the second half of the 18th century. Born in Paris, he was a pupil of the painter of ruins Giovanni Paolo Pannini and a former student at the French Academy in Rome, which he left in 1754 after a dispute with its director, Natoire.
In 1755 the Scottish architect Robert Adam arrived in Florence, where he met Clérisseau, who accompanied him to Rome; there Adam resolved, under the spell of Clérisseau, to produce a volume for publication upon his return that would establish him as a serious architect. The project he selected was a volume documenting the ruins of Diocletian's Palace at Split, easily accessible on the Dalmatian coast.
Over a period of five weeks in 1757 Adam sketched and supervised the documentation of the ruins, while Clérisseau produced perspectives, and two German draftsmen undertook the measured drawings. Most of the published engravings in Adam's Ruins of the palace of the Emperor Diocletian at Spalato are believed to be the work of Clérisseau, though he received no credit.
Clérisseau passed most of the next decades in Rome. As it had done since the High Renaissance, ancient Rome and modern Rome functioned as a cultural hub, the ruins of Classical Antiquity providing a school in themselves, if one had a knowledge
