Memoirs of Hadrian, historical novel by Marguerite Yourcenar, published in 1951 as Mémoires d’Hadrien.
In the book, Yourcenar creates a vivid and historically accurate portrait of the 2nd-century Roman Empire under Hadrian’s rule. The work is a fictional first-person narrative in the form of Hadrian’s letters—mostly to his nephew Marcus Aurelius—written shortly before his death. Contemplative and analytical recollections of his accomplishments, his hopes for Rome, and his personal relationships, the letters depict the emperor as a highly intelligent, often wise man, conscious of the great power he wields.
