All You Need to Know About Roman Names


Names are Identity. Names are powerful and a pointer to one’s culture or history. In relation to that, we are going to delve into Roman names. What do you know about Roman names? Roman names were typically composed of three elements: the cognomen (additional name or nickname), the nomen (family name), and the praenomen (given name).

Take Gaius Julius Caesar, for instance. The nomen denoted the gens or clan, the cognomen identified specific members of the gens, and the praenomen functioned similarly to a first name. The Romans had three names, unlike us, who only have a first and last name.

So basically, we can see that Roman names typically consisted of three parts, as explained below:

1. Praenomen (Forename)

In Roman names, a person’s birth name was their personal name. It was akin to a first name, according to modern naming practices. Marcus, Lucius and Gaius are a few examples. The most intimate name, used to identify a member of a family (e.g., Gaius, Lucius, Marcus).

2. Nomen

The nomen denoted the clan or gens (family) of the individual. It resembled a family name or surname. Flavius, Claudius, Cornelius, and Julius are a few examples. It’s a family name from the Greeks that sounds like our last names.

3. Cognomen (Surname)

To identify members of the same family or gens, a cognomen was a second name or nickname. It might be determined by personal traits, accomplishments, or other elements. It’s distinguished lines that once separated families; these lines later became inherited (e.g., Caesar, Cicero, Brutus).

Let’s also note the additional Points about the Romans names below:

  • Women: Women are usually limited to the cognomen and praenomen.
  • Adoption: Sons who were adopted assumed their adoptive father’s nomenclature and cognomen.
  • Nicknames (Cognomina): Term used interchangeably with formal names, depending on appearance, character or experiences in life.
  • Class Difference: Although the lower class may have had greater variance, the upper class adhered to the system more closely. This is evident in Roman names.

So an example of a complete Roman name might look like this: “Gaius Julius Caesar” would be the full form of a Roman name, with “Gaius” serving as the praenomen, “Julius” as the nomen, and “Caesar” as the cognomen.

Roman nomenclature changed over time to reflect changes in politics, society and culture. Names in the early Roman Republic (c. 509–27 BCE) usually had three components: the nomen (clan or gens name), the cognomen (family name) and the praenomen (personal name).

Praenomen were mostly used within the family circle and were frequently shortened to a single letter. The cognomen distinguished branches or individuals within the gens, whereas the nomen signified the individual’s clan or gens.

Other names were occasionally taken as Rome grew and its social systems evolved. For instance, throughout the late Republic and Empire era, several people received honorific titles or additional nicknames called “agnomina” in recognition of their accomplishments, personal qualities or military prowess, among other things. Notable instances consist of Gaius Julius Caesar, whose cognomen “Caesar” might have come from the thick hair of a forebear or from the Latin word “elephant.”

People frequently inherited three or more names from their family under the Empire, as naming customs grew more uniform. The phenomenon waned with time and was frequently condensed to a small number of standard decisions made by family members. Additionally, the cognomen grew less specific and was occasionally inherited, making it difficult to distinguish between people.

The emergence of Christianity and the fall of the Western Roman Empire brought about other changes in naming customs. By the Middle Ages, many people had only one name, which frequently reflected their occupation or place of origin and the use of praenomina had decreased.

Roman naming customs still influence modern naming practices, especially in Western nations where given names and surnames are prevalent. However, more straightforward naming structures have essentially taken the place of the intricate system of praenomina, nomina and cognomina.

To explain more about Roman names, let’s take a good look at a brief history of Roman names. Roman name history is an interesting trip reflecting the development of Roman society. Below is a summary of the main ideas:

Early Republic (Before 300 BC)

  • Simple System: The Roman Republic had a rather straightforward name system in its early years. People may have only had one name, frequently chosen according to their status or line of work.
  • Etruscan Influence: Rome’s naming customs started to change as it interacted with the nearby Etruscan civilization. The Romans adopted the nomen and praenomen systems employed by the Etruscans.

Middle Republic (300 BC – 100 BC)

  • Standardization of Praenomina: During this time, the number of frequently used Praenomina decreased. Quintus, Gaius, Lucius, Marcus and Tiberius were among the most popular possibilities.
  • Rise of the Cognomen: Originally, a gens’ (clan’s) cognomen was used to identify its several branches. The importance of the cognomen for distinguishing increased with the size of families.

Late Republic and Early Empire (100 BC – 200 AD)

  • Cognomina as Surnames: By this time, the cognomen had become a hereditary surname, much like our own last names.
  • Multiple Cognomina: In order to set themselves apart even more, prominent families within a gens may take on extra cognomina. Gaius Julius Caesar, for instance, may be called Gaius Julius Caesar Augustus.
  • Women and Naming: Traditionally, women were only given a cognomen and a praenomen. Traditionally, men were assigned the gens (nomen).

Later Roman Empire (200 AD – 476 AD)

  • Foreign Names: Foreign names started to be incorporated into or adopted from the Roman naming system as the Roman Empire grew.
  • Multiple Praenomena: Although rare, certain people may have possessed more than one praenomen.

Interesting Aspects:

  • Meaningful Cognomina: Certain cognomina, such as Brutus (“heavy”) and Cicero (“chickpea”), had descriptive connotations. Not every cognomina, nevertheless, could be translated directly.
  • Nicknames (Cognomina): Romans frequently used nicknames in addition to their formal names or cognomina. These monikers could be derived from notable events in life, psychological qualities or physical characteristics.
  • Adoption: As part of their integration into their new family line, adopted males would assume the nomen and cognomen of their adoptive father. Adoption was a popular procedure.
