Schinkel/Campo Marzio connection 9020e
I just noticed, yesterday, a similarity between the plans of the monuments to Julius Caesar and Augustus in the Area Martis and one of the monuments to Friedrich the Great by Schinkel . Moreover, there is also a similarity between the round rooms within the Horti Agrippinae and the lower level of the rotunda of the Altes Museum . These similarities make me curious as to whether Schinkel was inspired and/or influenced by the Piranesi plan diagrams. Schinkel did spend time in Rome, and there is also the link to Piranesi via Durand.
In any case, it is an interesting coincidence, and whether or not Schinkel actually noticed the plans in the Ichnograpia of the Campo Marzio may not be all that important because regardless of the actual historical truth, the fact that I am now making the connection is now part of history and a comment on the fluidity of architectural history.
