This event was celebrated by Delavigne in a Dithyrambe sur la naissance du roi de Rome, which secured for him a sinecure in the revenue office.
Delavigne, inspired by the catastrophe of 1815, wrote two impassioned poems, the first entitled Waterloo, the second, Devastation du musee, both written in the heat of patriotic enthusiasm, and teeming with popular political allusions.
Twenty-five thousand copies were sold; Delavigne was famous.
The latter piece-obtained a longer lease of life than its intrinsic literary merits warranted, on account of the popularity of the political opinions freely expressed in it - so freely expressed, indeed, that the displeasure of the king was incurred, and Delavigne lost his post.
Accordingly Delavigne became librarian at the Palais Royal, a position retained during the remainder of his life.
