Annia Galeria Faustina Minor (c. 130–175/176) — daughter of Antoninus Pius and Faustina the Elder, cousin and, from 145, wife of Marcus Aurelius. She bore him many children (of the survivors, Commodus and Lucilla). She accompanied Marcus on campaign and received the title mater castrorum ("mother of the camps"). She died in the East c. 175; Marcus deified her and founded the puellae Faustinianae (a charity for girls) in her memory. A later hostile tradition (SHA) charged her with debauchery — hence the tart footnote in translators (Petrarch: "he might have been called happy, had he not had Faustina for a wife and Commodus for a son"); the historical reliability of these charges is doubtful.

• 01-17 — in the list of thanks to the gods: "so devoted, so affectionate, so frank a wife" (τοιαύτη … ἡ γυνή). The one direct, warm mention of his wife in the whole corpus — an important testimony to Marcus's domestic peace, against the later slander.

SHA Marcus 19, 26; Cassius Dio 71–72; A. Birley, Marcus Aurelius: A Biography, chs. 4, 9. To be distinguished from her mother: Antoninus Pius was her father, and her mother was Faustina the Elder.
