When people search for the Michelangelo surname, they are usually trying to answer a simple question with a slightly surprising answer: Michelangelo is not a surname at all, but a first name. The artist known to the world as Michelangelo had the full name Michelangelo di Lodovico Buonarroti Simoni, and his family name — his surname — was Buonarroti. This guide explains the Michelangelo surname question in full: why the artist is known by his first name, what Buonarroti means and where it came from, how Italian naming worked in the Renaissance, and how to refer to him correctly.
The confusion is understandable. In English, we usually refer to famous people by their surnames — Shakespeare, Beethoven, Einstein — so a search for “Michelangelo surname” feels natural. But Renaissance Italy followed different conventions, and artists of the period are often known by first names, nicknames, or place names instead. Understanding those conventions clears up not only Michelangelo’s name but also those of Leonardo, Raphael, and their contemporaries.
Michelangelo Surname: Buonarroti
Michelangelo’s surname was Buonarroti, sometimes written Buonaroti in older documents, from a family of Florentine bankers and minor nobility. His father, Lodovico di Leonardo Buonarroti Simoni, held civic offices in Florence, and the family claimed descent, with varying degrees of plausibility, from earlier Florentine lineages. The full name, Michelangelo di Lodovico Buonarroti Simoni, follows the Italian pattern of the time: given name, patronymic (“son of Lodovico”), family name, and an additional family branch name.
The name Buonarroti itself is thought to derive from the Italian elements buono, meaning “good”, and arroti, a form related to acquiring or adding — roughly, “well-acquired” or “of good fortune”, though the exact medieval origin is debated by historians of Italian names. What is certain is that it was the family name Michelangelo inherited, used in official documents, contracts, and letters, even though the public and posterity came to know him by his first name alone.
Michelangelo Surname: Why He Is Known by His First Name
Renaissance artists were often known by their first names because first names, combined with a place or a nickname, were distinctive enough in small artistic communities, and because the modern habit of surname-only reference had not yet hardened. Leonardo da Vinci is known as Leonardo, with “da Vinci” meaning “from Vinci”, his birthplace, not a surname. Raphael is known as Raphael, short for Raffaello Sanzio, where Sanzio is the family name. Michelangelo follows the same pattern: a single, sonorous first name that became a brand in itself.
Michelangelo’s first name also suited his self-image. He signed works and letters as “Michelangelo”, and sometimes as “Michelangelo Buonarroti”, but the single name carried an authority that a full formal name did not. By the time of his death in 1564, “Michelangelo” alone meant the artist, just as “Leonardo” alone meant his great contemporary. Later art history kept the convention, and today, referring to “Buonarroti” without context would puzzle most readers, while “Michelangelo” is instantly understood.
Michelangelo: The Name’s Meaning
The given name Michelangelo combines two elements: Michael, from the Hebrew Mikha’el, meaning “who is like God?”, and Angelo, the Italian form of Angelus, meaning “angel” or “messenger”. The combined name thus means, loosely, “Michael the angel” or “angelic Michael”, and it was a devotional name, honouring both the Archangel Michael and the idea of angelic protection. It was not uncommon in Renaissance Italy, but Michelangelo Buonarroti made it uniquely his own.
The name’s religious resonance suited an artist whose greatest works — the Sistine Chapel ceiling, the Last Judgement, the Pietà, the David — are steeped in Christian theology and humanist philosophy. Whether the name shaped the career or the career sanctified the name is a question for biographers, but the fit between the name’s meaning and the work’s ambition is striking, and it is one reason the single name has endured: it sounds like the artist it denotes.
How to Refer to Him Correctly
In formal writing, the safest practice is to give the full name on first mention — Michelangelo Buonarroti — and then to use “Michelangelo” thereafter, which is the standard art-historical convention. Referring to him as “Buonarroti” alone is technically correct as a surname reference, but it is uncommon and may confuse readers who expect the familiar form. In a family-history or genealogical context, however, “Buonarroti” is the name to search: parish records, contracts, and civic documents will list him under the family name, often with the patronymic and branch name included.
The same caution applies to his contemporaries. Searching for “Leonardo surname” leads to the same kind of answer: Leonardo’s family name was not “da Vinci”, which is a place description, and his father’s name was Piero, giving the patronymic “di Piero”. Renaissance naming repays a little patience, because it follows its own logic, and that logic explains many apparent puzzles in art history.

| Artist | Commonly known as | Family name | Full name |
|---|---|---|---|
| Michelangelo | Michelangelo | Buonarroti | Michelangelo di Lodovico Buonarroti Simoni |
| Leonardo | Leonardo da Vinci | — (da Vinci is a place name) | Leonardo di ser Piero da Vinci |

| Donatello | Donatello | di Niccolò di Betto Bardi | Donato di Niccolò di Betto Bardi |
The Buonarroti Family Background
The Buonarroti were a respectable Florentine family, though not among the city’s great banking dynasties. Michelangelo’s father, Lodovico, held municipal offices, including a term as podesta, or chief magistrate, of the small town of Caprese, where Michelangelo was born in 1475, and later posts in Florence itself. The family owned property and claimed a lineage reaching back to the counts of Canossa, a claim modern historians treat with scepticism but which the family itself took seriously. For a younger son of such a family, art was not the expected career: banking, law, or civic office would have been more conventional, and Lodovico initially resisted his son’s wish to become an artist.
That resistance matters for understanding Michelangelo’s name. When he signed contracts and letters, he used the family name with pride, and he was conscious of his social standing in a way that many artists of humbler birth were not. Yet he also understood the power of a single name. In the art world of Florence and Rome, where workshops were known by their masters’ first names and where a reputation travelled by word of mouth, “Michelangelo” was enough. The family name remained for documents; the first name became the legend, and the tension between the two — between the Florentine gentleman and the divine artist — runs through his biography.
Signature and Self-Image
Michelangelo rarely signed his sculptures, famously making an exception for the Pieta in St Peter’s Basilica, where he carved his name across the Virgin’s sash after hearing the work attributed to another sculptor. The anecdote, told by his contemporary biographers, captures his attitude to naming: he did not need to sign his work, because his style was his signature, but he would not tolerate misattribution. For paintings and drawings, signatures were even rarer, and attribution rests on style, documents, and contemporary accounts rather than on a name written on the work.
That attitude helps explain why the surname question arises at all. Modern viewers, used to signed and branded art, expect a surname on the label, and they look for “Buonarroti” as the answer. Art history gives them “Michelangelo” instead, because that is how the artist was known in his lifetime and how he has been known ever since. Both names are correct; they simply belong to different contexts, one documentary and one cultural, and knowing which to use when is part of writing about art well.
Buonarroti in Documents and Archives
Researchers looking for Michelangelo in archives should search under Buonarroti, and should expect spelling variation. Renaissance documents use Buonarroti, Buonaroti, and occasionally Bonarroti, reflecting inconsistent spelling before standardisation, and the patronymic “di Lodovico” helps distinguish Michelangelo from other Buonarroti of the same period. Florentine civic records, the archives of the Opera del Duomo, and the Vatican archives all hold material under the family name, including contracts for the Sistine Chapel, letters to family members, and accounts for marble purchases. A search that combines the family name with a date range and a place — Florence in the 1490s, Rome in the 1500s — will usually find relevant material faster than a search on the first name alone.
