   “this mental phantasmagoria”

   “1874, Marcus Clarke, For the Term of His Natural Life Chapter V It is impossible to convey, in words, any idea of the hideous phantasmagoria of shifting limbs and faces which moved through the evil-smelling twilight of this terrible prison-house. Callot might have drawn it, Dante might have suggested it, but a minute attempt to describe its horrors would but disgust. There are depths in humanity which one cannot explore, as there are mephitic caverns into which one dare not penetrate.”

   “What’s happening at the Post now — I’m surprised more people haven’t drawn the comparison — is sort of comparable to the phantasmagoria of rake stomps which took place at The New Republic after Facebook billionaire Chris Hughes purchased it in 2012.”
