Any number of things set off my chronic weakness:

-Edward Lear's paintings of parrots, Man Ray's photograph Glass Tears, the glass of Emile Galle...the ceramic dishes of Bernard Palissy...

-Paradises, true and false: the Tea Palace in Mantova is a prime example...

-The serpents painted by Jacopo Ligozzi, anything painted by Bosch or Maria-Sybilla Merian...Tenniel's illustrations for Alice

-A mural painted by Max Ernst for Paul Eluard's house called Au Premier mot limpide..

-Tumeric....the books of Jurgis Baltrusaitis

-Palenque

-The entire bestiary of Aloys Zotl

-Capricorn beetles

-..a glass by Dale Chihuly...
