# Metrodorus (grammarian)

**Metrodorus** (Greek: Μητρόδωρος; fl. c. 6th century) was a Greek grammarian and mathematician, who collected mathematical epigrams which appear in the *Greek Anthology*.

Nothing is known about the life of Metrodorus. The time he lived is not certain: he may have lived as early as the 3rd century AD, but it is more likely that he lived in the time of the emperors Anastasius I and Justin I, in the early 6th century.^{[1]}

His name occurs in connection with 45 mathematical epigrams which are to be found in book 14 of the *Greek Anthology*.^{[2]} Although he may have authored some of the epigrams, it is generally accepted that he collected most of them, and some of them may predate the 5th century BC.^{[1]} Many of the epigrams lead to simple equations, and they are of the same type as those found in the Rhind Mathematical Papyrus (17th century BC).^{[3]} Among the problems Metrodorus collected are:^{[3]}

- Twenty-three simple equations with one unknown, one of which is the famous epigram which reveals the age of Diophantus.
^{[4]}
- Twelve are easy simultaneous equations with two unknowns.
- One gives a simultaneous equation with three unknowns.
^{[5]}
- Six are problems about filling and emptying vessels by pipes.
