Surprise! David Toop in Sinister Resonance: The Mediumship of the Listener (see prev. post ) does not refer to the Laocoon marble. Granted, Toop mentions The Scream by Munch, which is the direct heir to the Laocoon.
The Laocoon is central to the ekphrasis concept, and the ekphrasis concept should be central to the “Act of silence” and “Art of silence” chapters in Sinister Resonance.
In fact, the whole area of writing about music is an act of ekphrastic transposition, some have even found completely nonsensical, testimony to this is the famous maxim “writing about music is like dancing about architecture.”
