Vienna and the unconscious.
Regretfully the author of another of my 2-3 interesting uni books (see also the-greeks-and-the-kill) passed away, at the acquired age of 100 years.
His book Fin-de-Siécle Vienna was an eye opener for me as it lay bare the influence of the unconscious (and the discovery thereof) in the Arts, in all its varied utterances.
On his passing see here (nyt).
Update: Still some copies of his magnificent Fin-de-Siecle-Vienna for sale at boekwinkeltjes.nl (for a friendly 8 euriis) !
And support your local book vending brotherhood, they have it tough !
