Off List, in relation to the quote
from Chekhov's story "At Home" ["in his mind, sound was intimately
connected with form and colour, so that in painting letters he invariably
coloured the sound L, yellow; M, red; A, black, and so forth" :Anton Chekhov -
Selected Stories, by J.Andrew, Wordsworth Classics, pages 21-24], I was
informed that it "might have been VN's first notice of synaesthesia in
print. Intriguing."
More information:
"At Home" was first published as "Doma" in New
Times ( 7 March, 1887), later in the collection "In the Dusk", published in
St.Petersburg in 1887 and, later, in various other collections.
(It was praised by Tolstoy, who "considered it to be
one of Chekhov's best", following J.Andrew's footnote n.4).
