Some Roman men, particularly aristocrats, had more than three names — often because they were adopted or accepted an inheritance, linking them to additional family members. One senator in the second century CE had a whopping 38 names, six of which came from his father. By the fifth century CE, multiple names had mostly fallen out of use, and after that Roman citizens typically went by just one name. Middle names came back into vogue in Renaissance Italy, when families would give their children Catholic saint names in hopes the saints would protect them. This paved the way for middle names as we know them today, although the practice didn't catch on in Britain or the United States until the 19th century.

By the Numbers

Pablo Picasso had around 15 names.

The common moniker "Pablo Picasso" is actually only a small fraction of the famous painter's full name. When he was born in 1881 in Andalusia, Spain, his family gave him around 15 names (sources vary), taken both from saints and members of his own family. The exact order is unclear, but his full name was along the lines of Pablo Diego José Francisco de Paula Juan Nepomuceno Crispín Crispiniano María de los Remedios de la Santísima Trinidad Ruiz Picasso. His first name, Pablo, came from an uncle who had died a few years before he was born. It actually took a while for Picasso to settle on which names to use in his signature. He signed his earliest paintings P. Ruiz, then P. Ruiz Picasso, then P.R. Picasso, before settling 0n Picasso.
