Etymology & Historical Origin - Caius

 Caius/Gaius is an Old Latin praenomen, a boy’s given name chosen by his parents, in the Roman Republic’s three-part naming system (known as the Tria Nomina) – comprised of the praenomen, the nomen, and the cognomen – or, in modern-speak, the personal name, the family name, and the nickname).  Like Lucius, Marcus, Octavius and Titus, Gaius was an extremely common given name in Ancient Rome (think: Gaius Julius Caesar).  Caius is a variant spelling, reflecting the early Roman confusion regarding the use of gamma (which they used for both the “g” and “k” sounds, having little use for the Greek kappa).  The origin of Gaius is most likely Etruscan (an extinct Italic language eventually replaced with Latin), so the name’s meaning is not entirely known/certain.  There are some theories, however.  For one, the Late Latin “gaius” was the word for the jay or magpie (as in the chatty, colorful bird), possibly stemming from the ancient praenomen.  Others theorize the word is related to the Proto-Indo-European (prehistoric) root *ghel- meaning “to shine” from which the Latin “gavisus” (glad, rejoicing) finds its hypothetical origin. We like the theory that Gaius means “happy, rejoicing” in keeping with Ancient Rome’s naming system and how other masculine praenomina reflected positive attributes: for example, Faustus (lucky, fortunate) and Lucius (light).  The name Gaius also appears in the Biblical New Testament as a companion of Saint Paul.

Popularity of the Name Caius

 Neither Gaius nor Caius has ever been a popular enough masculine name in America to land a spot on the U.S. Top 1000 list. Case in point, the name Caius was given to 108 baby boys in 2013 while Gaius was given to a mere 29.  While common in the days of the Ancient Roman Republic, today these names are really quite rare.  We like the history and the theorized etymologies – and we love the connection to Gaius Julius Caesar (famed conqueror of Gaul) as well as Gaius Octavius, known simply as Augustus (i.e., venerable).  Caius and Gaius – both abbreviated as C. – are among the oldest names in Western Civilization.

    Gaius Julius Caesar (100 B.C. – 44 B.C.) - Probably one of the most well-known names of Ancient Rome, Gaius Julius Caesar played a seminal role during the transformation of Rome from a Republic to an Empire. First as a Roman military leader, Caesar made his name by conquering Gaul (Western Europe which was then populated by Celtic tribes) and by orchestrating the first British invasion. He is most famous for uttering these three words after his military triumphs: Veni, vidi, vici (I came, I saw, I conquered). Due to his military success on behalf of the ever-expanding Roman Empire, Caesar’s popularity back at home skyrocketed (particularly among the plebeian and middle classes) – his political power grew in spades. Not only did he defeat his one-time political ally, Pompey, but he also spent some time in Egypt (where he had a dalliance – and a son – with Cleopatra). He was eventually made “Dictator for Life” back in Rome and the month of July was renamed in his honor (formerly known as Quintilis). Caesar would ultimately meet a violent death on the floor of the Roman Senate on the Ides of March in 44 B.C. at the hands of his former friends (Et tu, Brute?) – he had alienated his political peers as his ambitions (and ego) grew with his power. His assassination – and the civil unrest that followed – marked the end of the Roman Republic.
