Римское имя: происхождение и эволюция триа номина.

Personal given name in Ancient Rome
the pharaonic throne name
The praenomen (; plural: praenomina) was a personal name chosen by the parents of a Roman child. It was first bestowed on the dies lustricus (day of lustration), the eighth day after the birth of a girl, or the ninth day after the birth of a boy. The praenomen would then be formally conferred a second time when girls married, or when boys assumed the toga virilis upon reaching manhood. Although it was the oldest of the tria nomina commonly used in Roman naming conventions, by the late republic, most praenomina were so common that most people were called by their praenomina only by family or close friends. For this reason, although they continued to be used, praenomina gradually disappeared from public records during imperial times. Although both men and women received praenomina, women's praenomina were frequently ignored, and they were gradually abandoned by many Roman families, though they continued to be used in some families and in the countryside.

The tria nomina, consisting of praenomen, nomen and cognomen, which are today regarded as a distinguishing feature of Roman culture, first developed and spread throughout Italy in pre Roman times. Most of the people of Italy spoke languages belonging to the Italic branch of the Indo European language family; the three major groups within the Italian Peninsula were the Latino Faliscan languages, including the tribes of the Latini, or Latins, who formed the core of the early Roman populace, and their neighbors, the Falisci and Hernici; the Oscan languages, including the Sabines, who also contributed to early Roman culture, as well as the Samnites, and many other peoples of central and southern Italy; and the Umbrian languages, spoken by the Umbri of the Central Apennines, the rustic Picentes of the Adriatic coast, and the Volsci. In addition to the Italic peoples was the Etruscan civilization, whose language was unrelated to Indo European, but who exerted a strong cultural influence throughout much of Italy, including early Rome. The Italic nomenclature system cannot clearly be attributed to any one of these cultures, but seems to have developed simultaneously amongst each of them, perhaps due to constant contact between them. It first appears in urban centers and thence gradually spread to the countryside. In the earliest period, each person was known by a single name, or nomen. These nomina were monothematic; that is, they expressed a single concept or idea. As populations grew, many individuals might be known by the same name. Unlike the other cultures of Europe, which dealt with this problem by adopting dithematic names (names expressing two ideas), the peoples of Italy developed the first true surnames, or cognomina. At first these were generally personal names, and might refer to any number of things, including a person's occupation, town of origin, the name of his or her father, or some physical feature or characteristic. But gradually an increasing number of them became hereditary, until they could be used to distinguish whole families from one generation to another. As this happened, the word nomen came to be applied to these surnames, and the original personal name came to be called the praenomen, or "forename", as it was usually recited first. Cognomen came to refer to any other personal or hereditary surnames coming after the family name, and used to distinguish individuals or branches of large families from one another. As the tria nomina developed throughout Italy, the importance of the praenomen in everyday life declined considerably, together with the number of praenomina in common use. By the first century they were occasionally omitted from public records, and by the middle of the fourth century they were seldom recorded. As the Roman Empire expanded, much of the populace came from cultures with different naming conventions, and the formal structure of the tria nomina became neglected. Various names that were originally nomina or cognomina came to be treated as praenomina, and some individuals used several of them at once. However, some vestiges of the original system survived, and many of the original praenomina have continued into modern times. Most common praenomina were regularly abbreviated in writing (in speech the full name would always be used). Although some names could be abbreviated multiple ways, the following tables include only the most usual abbreviation, if any, for each name. These abbreviations continue to be used by classical scholars.

Each of the Italic peoples had its own distinctive group of praenomina. A few names were shared between cultures, and the Etruscans in particular borrowed many praenomina from Latin and Oscan. It is disputed whether some of the praenomina used by the Romans themselves were of distinctly Etruscan or Oscan origin. However, these names were in general use at Rome and other Latin towns, and were used by families that were certainly of Latin origin. Thus, irrespective of their actual etymology, these names may be regarded as Latin.

Many families, particularly amongst the great patrician houses, limited themselves to a small number of praenomina, probably as a means of distinguishing themselves from one another and from the plebeians, who used a wider variety of names. For example, the Cornelii used Aulus, Gnaeus, Lucius, Marcus, Publius, Servius, and Tiberius; the Julii limited themselves to Lucius, Gaius, Sextus, and Vopiscus; the Claudii were fond of Appius, Gaius, and Publius; the Postumii favored Aulus, Gaius, Lucius, Publius, and Spurius; and so on. The most prominent plebeian families also tended to limit the names of which they made regular use, although amongst both social classes, there must have been exceptions whenever a family had a large number of sons. Many families avoided certain names, although the reasons varied. According to legend, the Junii avoided the names Titus and Tiberius because they were the names of two sons of Lucius Junius Brutus, the founder of the Republic, who were executed on the grounds that they had plotted to restore the king to power. Another legend relates that after Marcus Manlius Capitolinus was condemned for treason, the Roman Senate decreed that no member of gens Manlia should bear the praenomen Marcus, a tradition that seems to have been followed until the first century. However, normally such matters were left to the discretion of the family. In most instances, the reason why certain praenomina were preferred and others avoided probably arose from the desire to pass on family names. Several names were used by only a few patrician families, although they were more widespread amongst the plebeians. For example: Appius was used only by the Claudii, Caeso by the Fabii and the Quinctii, Agrippa by the Furii and the Menenii, Numerius by the Fabii, Mamercus by the Aemilii and the Pinarii, Vopiscus only by the Julii, and Decimus was not used by any patrician family (unless the Junii were, as is sometimes believed, originally patrician), although it was widely used amongst the plebeians. Throughout Roman history, the most common praenomen was Lucius, followed by Gaius, with Marcus in third place. During the most conservative periods, these three names could account for as much as fifty percent of the adult male population. At some distance were Publius and Quintus, only about half as common as Lucius, distantly followed by Titus. Aulus, Gnaeus, Spurius, Sextus, and Servius were less common, followed by Manius, Tiberius, Caeso, Numerius, and Decimus, which were decidedly uncommon (at least amongst the patricians) during the Republic. Throughout Republican times, the number of praenomina in general use declined, but older names were occasionally revived by noble families, and occasionally anomalous names such as Ancus, Iulus, or Kanus were given. Some of these may have been ancient praenomina that had already passed out of common use by the early Republic. As they vanished from use as personal names, many older praenomina, such as Agrippa, Faustus, Mamercus, Paullus, Postumus, Proculus, and Vopiscus were revived as cognomina. Other examples of names that may once have been praenomina include Fusus, an early cognomen of gens Furia, and Cossus, a cognomen of gens Cornelia. By the first century BC, the praenomina remaining in general use at Rome were: Appius, Aulus, Caeso, Decimus, Gaius, Gnaeus, Lucius, Mamercus, Manius, Marcus, Numerius, Publius, Quintus, Servius, Sextus, Spurius, Titus, and Tiberius. However, older names continued to be revived from time to time, especially in noble families, and they probably continued to be used outside Rome. By the second century, several of these names had also passed out of general use at Rome, leaving Aulus, Decimus, Gaius, Gnaeus, Lucius, Manius, Marcus, Numerius, Publius, Quintus, Sextus, Titus, and Tiberius. Under the empire, confusion seems to have developed as to precisely what constituted a praenomen and how it should be used. A number of emperors considered Imperator as a praenomen, and thus part of their names. As a larger percentage of the Roman populace came from backgrounds that had never used traditional Roman names, the praenomen was frequently omitted, or at least ignored. In its place, an increasing number of magistrates and officials placed common nomina, frequently with praenomen like abbreviations. The most common of these were Flavius (Fl. ), Claudius (Cl. ), Julius, Junius, Valerius (Val. ), and Aurelius. These names appear almost arbitrarily, much like praenomina, and probably were intended to imply nobility, although ultimately they became so common as to lose any real significance.

The Etruscan language was unrelated to the other languages spoken in Italy, and accordingly it contains many names which have no equivalents in the Latin or Oscan languages. The Etruscan civilization, the most advanced of its time in that region, was a strong influence on the other peoples of Italy. The Etruscan alphabet (itself based on an early version of the Western or "Red" Greek alphabet) was the source for later Italian alphabets, including the modern Latin alphabet. However, the cultural interchange was not all one way. With respect to personal names, the Etruscans borrowed a large number of praenomina from Latin and Oscan, adding them to their own unique names. The Etruscan language is still imperfectly known, and the number of inscriptions are limited, so this list of Etruscan praenomina encompasses what has been discovered to this point. Included are names that are certainly praenomina, no matter their linguistic origin. Names that might be nomina or cognomina have not been included.
