Fortunatus

A Latin masculine personal name and Roman cognomen meaning “fortunate” or “lucky,” attested in Roman inscriptions and in Paul’s First Letter to the Corinthians.

Fortunatus is a Latin masculine name whose plain sense is “fortunate,” “lucky,” or “prosperous.” Romans used it as a cognomen, and it later continued as a Christian personal name. The familiar Romance-language form Fortunato developed from the same Latin name.

The meaning is favourable or augurative: it expresses good fortune wished for or associated with the bearer. It is not evidence that a historical Fortunatus was rich, unusually lucky, or considered divinely favoured.

Meaning and Linguistic Formation

Latin Fortūnātus began as an adjective. Lewis and Short’s Latin dictionary derives it from the verb fortūnō, “to make prosperous or fortunate,” which in turn belongs to the word family of fortūna, “fortune” or “luck.” The dictionary gives a range from “lucky” and “happy” to “prosperous”; in some contexts the adjective can also mean well-to-do or wealthy.

That range matters when translating the name. “Fortunate” or “lucky” is the safest concise meaning. “Blessed,” “happy,” and “prosperous” can convey parts of the Latin sense, but none should be treated as a separate origin. “Rich” is a contextual meaning of the adjective, not a promise contained in every use of the personal name.

The feminine Latin form is Fortunata. Both forms are transparent Latin word-names: their favourable sense would have been intelligible to a Latin speaker.

A Roman Cognomen and Wish-Name

Fortunatus was not originally a modern-style first name or family surname. It belonged to the much more flexible Roman naming system and is documented as a cognomen. A cognomen could distinguish an individual, become inherited in some families, or serve as the personal name retained by a freed person. It therefore cannot be mapped mechanically onto either “middle name” or “surname.” The Oxford Handbook of Roman Epigraphy explains both this changing role and the eventual breakdown of the classical three-name system.

Historian Stephen Wilson groups Fortunatus with Felix, Faustus, and Victor as complimentary or protective wish-names that became more prominent in the imperial period. In other words, the name expressed an auspicious idea; it did not record an occupation, birthplace, or ancestry. (Wilson, *The Means of Naming*, pp. 14–15.)

A concrete epigraphic example comes from Roman Corduba, now Córdoba in Spain. Two inscribed altars name Publicius Fortunatus in 234 CE and Publicius Valerius Fortunatus in 238 CE. Clara María Ramos-Taboada argues that they probably refer to the same man, but treats his precise status through the complete inscriptions and their context—not through Fortunatus alone. Her study also notes the name among enslaved and freed people while warning that one onomastic marker is insufficient to prove status. (Ramos-Taboada, 2024.)

This is an important genealogical limit. An ancient inscription containing Fortunatus does not establish that later people with the name descend from that bearer, and the name itself does not prove Roman citizenship, slavery, manumission, or membership in a particular family.

The Fortunatus Named by Paul

One securely dated early Christian occurrence is in 1 Corinthians 16:17–18. The letter, usually dated to 53–55 CE and probably written from Ephesus, names Fortunatus together with Stephanas and Achaicus. Paul says that their arrival refreshed his spirit and that of the Corinthians. (Oxford Bibliographies, “1 Corinthians”; Greek text of 1 Corinthians 16.)

In the surviving Greek text the name appears in the genitive form Φορτουνάτου (Phortounatou), a Greek rendering of the Latin name. This passage proves that a Christian named Fortunatus was known to Paul in the first century. It does not give his birthplace, parentage, age, occupation, or later life. Claims that identify him more fully belong to later tradition unless supported by separate evidence.

The New Testament occurrence also shows that Christian use did not create the name: Fortunatus already belonged to Roman naming vocabulary. Christianity supplied new contexts and later saintly associations for an existing Latin name.

Later Christian and Medieval Use

The name remained visible in late antique and medieval Christian culture. A particularly well-documented bearer is Venantius Fortunatus (about 540–600), the Italian-born Latin poet who travelled to Gaul and ultimately became bishop of Poitiers. Judith George’s scholarly study places his writing in the Merovingian world and describes his importance as both poet and historical figure. (George, *Venantius Fortunatus: A Latin Poet in Merovingian Gaul*.)

Several saints and martyrs were recorded under Fortunatus or Fortunato, but hagiographic lists require care. Treccani’s entry on saints of the name, for example, notes that one Roman martyr formerly listed as Fortunatus should actually be read as Fortunata. That correction is a useful reminder that a repeated name in a calendar or index does not by itself identify one person or one continuous tradition. (Treccani, “Fortunato, santo”.)

The name also appears in medieval and early modern texts. The Dictionary of Medieval Names from European Sources records English Fortunate in the Wycliffite Bible of 1395 and an Italian Fortunato in a source dated 1522–1532. These are language and documentary forms of the name, not evidence of a single family line. (DMNES, “Fortunate”.)

Fortunatus, Fortunato, and Inflected Record Forms

The Real Academia Galega’s name guide identifies Fortunato as the Spanish, Italian, and Portuguese equivalent and Fortunat as the Catalan form; Fortunata is the corresponding feminine form in several Romance languages. (Real Academia Galega, “Fortunato, Fortunata”.)

Latin grammar creates an additional record-reading complication. A masculine name ending in -us changes its ending according to its role in a sentence. Thus a document may use Fortunati for “of Fortunatus,” Fortunato for “to,” “by,” or “with Fortunatus,” and Fortunatum when the name is the object of a verb. The UK National Archives’ guide to declining Latin personal names explains this pattern for names of the same class.

Consequently, Fortunato in a Latin record is not automatically an Italian, Spanish, or Portuguese vernacular name: it may simply be an inflected form of Latin Fortunatus. The surrounding sentence, place, date, and parallel vernacular records determine which explanation fits.

Names such as Fortuna and Fortune share vocabulary or a broad semantic idea, but they should not automatically be treated as spelling variants of Fortunatus. The same caution applies to unrelated people called Fortunato: linguistic equivalence does not establish genealogical identity.

A Literary Look-Alike

Searches for the name often retrieve Fortunatus, the hero and title of an anonymous German prose narrative about a magical purse. The Bavarian State Library holds a copy printed at Augsburg in 1509 and catalogues it as Fortunatus: Eyne hystorye. This literary Fortunatus is a fictional character, not evidence for a historical bearer or family. (Bayerische Staatsbibliothek record.)
