However, in 1852, Ingres, then seventy-one years of age, married forty-three-year-old Delphine Ramel, a relative of his friend Marcotte d'Argenteuil. Ingres was rejuvenated, and in the decade that followed he completed several significant works, including the portrait of "Princesse Albert de Broglie, née Joséphine-Eléonore-Marie-Pauline de Galard de Brassac de Béarn". In 1853 he began the "Apotheosis of Napoleon I", for the ceiling of a hall in the Hôtel de Ville, Paris. (It was destroyed in May 1871 when the Paris Commune set fire to the building.) With the help of assistants, in 1854 he completed another history painting, "Joan of Arc at the Coronation of Charles VII". A retrospective of his works was featured at the Paris Universal Exposition of 1855, and in the same year Napoleon III named him a Grand Officer of the Légion d'honneur. In 1862 he was awarded the title of Senator, and made a member of the Imperial Council on Public Instruction. Three of his works were shown in the London International Exhibition, and his reputation as a major French painter was confirmed once more.
