I have found the
image of "Pompeianella" as described in Ada, or as noted below by Brian
Boyd. The image is "from a painting of Flora, reproduced [as a book cover]
courtesy of the useo Archeologico Nazionale, Napoli."
9.06-08: Pompeianella . . . Naples museum: MOTIF: painting location. 9.06: Pompeianella:
because of the Nicky and Pimpernella comic strip (6.02) and Stabiae's proximity
to Pompeii. MOTIF: Pompeianella.
9.07: picture
books: see 8.31n. 9.07-08: but whom I admired last summer in a Naples museum:
Nabokov himself, at the time of writing Ada, had just been travelling in
Italy looking at museums in small towns and large cities for a projected but
never written Butterflies in Art. He visited Naples and the Museo
Nazionale di Napoli--where a large proportion of the relics from Pompeii,
Herculaneum and Stabiae are housed--in May 1966 (VNAY 512).
