"Les exilés"

Autograph poem by Théodore de Banville, unsigned, entitled "Les exilés," comprising 20 lines in black ink with deletions and corrections.
Vertical and horizontal fold marks from mailing.
In the upper right-hand corner, the poet has written: “envoi de livre à Don Bernardo Calderon.”
This four-quatrain poem appears to be unpublished and was seemingly not included in the collection "Les exilés" published in 1867.
«Ce  livre, pleurant  sur la gloire
Et sur le bonheur envolé,
Renferme toute notre histoire?
Qui donc n'est pas un exilé ?
[...]

Heureux celui qui sous la mer,
Penchant son triste front blémi,
Poursuit sa route aride et nue
En tenant la main d'un ami !... »

Fine quatrain by Théodore de Banville, likely unpublished.
