VILLIERS de LISLE-ADAM (Auguste). Isis. I. Paris : Dentu, 1862. - In-8, brown half-maroquin with corners, spine gilt, untrimmed, cover preserved (Champs). Very rare first edition, printed at author's expense at only 100 copies. This philosophical novel was supposed to include 7 parts or volumes, hence the mention "first part" on the cover, but it was the only one that appeared. Beautiful copy in Champs binding, enriched with an autograph letter signed by the author to the writer and journalist Henry de Pène (1830-1888) : " To Mr. Henri (sic) de Pène, // Ct Auguste Villiers de Lisle-Adam " Traces of folds and small tears to the cover .
