Name. Domitia Lucilla, daughter of P. Calvisius Tullus Ruso (consul 109) and Domitia Lucilla Maior. She bears her mother's name, and to tell them apart modern literature usually calls her Domitia Lucilla Minor (the Younger); the name Domitia Calvilla is also found. She inherited her mother's colossal fortune. Lucilla the Elder was the biological daughter of Cn. Domitius Lucanus and the adopted daughter of his brother, her uncle, Cn. Domitius Tullus; through this adoption and inheritance the Domitian fortune came together in her hands (see Eck 1978 on the legal details). Tullus's widow, Dasumia Polla, married L. Catilius Severus, which is why Marcus calls him his great-grandfather (see catilius-severus and 01-04).

Family. Her husband was M. Annius Verus the younger (see marcus-annius-verus-the-younger), a praetor who died around 124. Their children were Marcus (the future emperor, born 26 April 121) and Annia Cornificia Faustina (Marcus's younger sister). After her husband's death she remained a widow and did not remarry. Marcus's upbringing was undertaken in the first place by his consular grandfather M. Annius Verus the elder, into whose house Marcus formally passed by adoption; but Domitia Lucilla continued to be for Marcus a figure of everyday maternal presence — to judge both from 01-03 and from Fronto's correspondence (in which Marcus regularly enquires about his mother's health and sends his regards to her).

Fortune. Through the maternal line she inherited the figlinae — brick and tile workshops in the environs of Rome. The products of these workshops (stamped bricks and tiles bearing the legend ex figlinis Domitiae Lucillae and derivative formulae) are archaeologically documented in great quantity throughout the centre of the empire — the principal building material of the second century for large civic and private projects in Rome and Latium, including state works under Hadrian and Antoninus. This made her one of the wealthiest private individuals in Rome and a major economic player in the Roman construction market. After her death the figlinae passed to Marcus, and from there to the imperial fiscus.

Education and Greek culture. She was fluent in Greek, both in writing and in conversation (more than average for a Roman matron of her generation, though not unique). Fronto's correspondence contains letters addressed to her personally in Greek — a characteristic sign that correspondence with her did not require the mediation of Latin. She regularly received Greek philosophers, rhetoricians, and grammarians in her house. Through this domestic environment Marcus, already in childhood, absorbed bilingualism and Greek philosophical culture, which prepared him for the more systematic instruction under Junius Rusticus, Apollonius, and Sextus (see the corresponding passages 01-07 through 01-09).

Death. The date is not securely known. Birley, on the basis of indirect indications, gives a range 155–161 — after this Lucilla's name ceases to appear in Fronto's correspondence; the terminus ante quem is the beginning of Marcus's reign (161), by which point she was no longer alive.

Ethical portrait

Marcus characterises his mother by four qualities (see 01-03 and the commentary): θεοσεβές (piety), μεταδοτικόν (generosity), ἀφεκτικόν not only from deeds but even from thoughts (inner vigilance), and λιτὸν κατὰ τὴν δίαιταν (simplicity of daily life, kept far from the πλουσιακὴ διαγωγή). Three observations on the structure of this characterisation:

1. Family, not school, register. None of the four qualities is a canonical Stoic term from the list of the four cardinal virtues. They are Latin pietas, liberalitas, abstinentia/continentia, frugalitas in a Greek dress. Marcus, as also with the father (01-02: ἀρρενικόν instead of the canonical ἀνδρεία), preserves the household vocabulary.
2. Simplicity as a deliberate choice. Of all Roman matrons of her rank, Lucilla was one of the wealthiest; "a simple manner of living, far removed from the πλουσιακὴ διαγωγή" is not the simplicity of economy compelled by necessity but a choice, a demonstrative distancing from the social style expected of her. Stoically this illustrates the right handling of ἀδιάφορα: wealth is neither bad nor good, and the right relation to it is shown precisely in how it is (not) used. This disposition Marcus carries forward when he becomes emperor — cf. Med. 6.30 ("to live, as far as possible, at court in the simplest way").
3. Early formation of inner discipline. The thesis "to refrain not only from deeds but even from thoughts" is one of the programmatic statements of the whole Meditations and one of the principal loci of Stoic interiorisation of ethics. By ascribing this discipline to his mother, Marcus communicates that Stoic inner vigilance was not for him an intellectual discovery in his adult years — it was part of the family habitus from childhood, prior to systematic philosophical schooling.

External corpus: Fronto

The principal external source on Domitia Lucilla is Fronto's correspondence. Among the surviving letters are several addressed directly to her in Greek (for example, Ad M. Caes. 2.15: birthday wishes for her health). In his letters to Marcus himself, Fronto regularly enquires after her health, sends his greetings, and refers to her opinions on matters shared with her. From this corpus one can reconstruct the picture of a woman of refined Greek learning, sustaining a domestic philosophical-literary circle and possessing her own intellectual reputation in her son's environment.

• 01-03 — the only direct mention in the Meditations, with the four virtues ascribed to her.
• 01-17 — in the closing thanksgiving paragraph Marcus mentions "τὸ τυχεῖν τοιαύτης μητρός" ("that I came to have such a mother") among the goods for which he gives thanks to fortune and the gods; a secondary, more general reference.
