From A Bibliography of Alexandre Dumas père by Frank Wild Reed: Twelve lines, rhyming alternately.
Dumas was very fond of his mother, as he well might be. She died on the 1st of August, 1838, and Amaury Duval made a sketch of her as she lay after death. Beneath it her son wrote these lines. Glinel included them in his "Alexandre Dumas et Son Œuvre," 1884, page 355. Blaze de Bury did so also in his " Alexandre Dumas," 1885. page 314. Lecomte (L. Henry) printed them in his "Alexandre Dumas" (1902), page 45.
They may also be read in H. A. Spurr's "Life and Writings of Alexandre Dumas," 1902, pages 70 and 71; where he gives also the translation in English prose ; he also gives a reproduction of Duval's sketch which gave rise to them. Spurr's work was re-issued in 1929, but different in pagination, and in this edition the lines will be found on page 59.
