There are many schools out there the claim they are teaching in the classical tradition who are not teaching anything remotely close, and have little or no direct linage to those traditions.
The Gold Standard in traditional training in Architecture, Drawing, Painting, and Sculpture, with a 250 year linage, is the Repin Academy in Saint Petersburg, Russia.
Because of its being a state sponsored and funded organization it has retained the core of its Beaux-Arts foundation.
The majority of the programs in the current ‘Atelier’ movement are only doing lip service to ‘classical’ tradition. Their ‘Realist’ focus is diametrically opposed to anything ‘classical’.
The pillars of classical aesthetics are, Truth, Beauty, and Virtue. The tradition is about authenticity not reality.
