# Diophantus

> An Alexandrian mathematician whose margin note became the most famous tease in math history — not his own note, but Fermat's, scribbled in a 1621 edition of his work claiming a proof "too large for this margin." The equations he left behind now anchor entire branches of number theory.

*3rd century Alexandrian Greek mathematician*

## Bio

Diophantus of Alexandria flourished around 250 CE and authored the Arithmetica in thirteen books, ten still extant, working through arithmetical problems solved by algebraic equations. Lagrange later called him "the inventor of algebra"; his methods became standard in Neoplatonic schools of late antiquity, then shaped medieval Arabic algebra after a 9th-century translation carried his concepts and procedures east. The 1621 Bachet edition found unexpected immortality when Pierre de Fermat annotated his copy with the Last Theorem in the margin. His legacy now extends beyond that famous marginal drama: Diophantine equations, Diophantine geometry, and Diophantine approximations are subareas of number theory named for him, and problems from the Arithmetica still stir work in abstract algebra.
