Aristo is a young Greek tutor employed by Captain Marcus who teaches Flavia, Nubia, Lupus and Jonathan Greek, philosophy and music. He has also helped them with their investigations on numerous occasions.


Aristo was born in the Greek city of Corinth. His father is Diogenes and he has a brother named Dion. Since a young age, he has shown great ability in academic and musical areas.

For the majority of the novels, he is hopelessly infatuated with Miriam bat Mordecai, Jonathan's sister, resulting in him fighting over her with Pliny the Younger in The Dolphins of Laurentum. After her death in childbirth he is distraught and takes to playing mournful music. He apparently fails to notice that Nubia loves him.

In The Fugitive from Corinth his family background is revealed. His younger brother, Dion, has always been envious of his seemingly perfect sibling and tries to murder him, but ends up injuring Marcus instead.

As the series progresses, Aristo becomes more and more important in the children's adventures, helping them on several occasions. He is shown to care deeply for them and always put their safety before his own.

In the final book, The Man from Pomegranate Street, he confesses his love for Nubia and marries her. It is revealed that he had known for some time that he loved her, but felt he could not tell her so, as he believed her to be in love with Flaccus.


Aristo is intelligent, humorous and kind, which causes many girls to be romantically interested in him. He is very helpful to the detectives, being flexible about what constitutes education.
He is shown to take responsibility very seriously, although this is more so in his twenties than in younger years, when he was a little prone to thoughtlessness.


He plays the lyre excellently and often accompanies Nubia when she plays the flute.
Aristo also speaks fluent Latin and Greek.

Physical AppearanceEdit

Aristo is described as being very handsome, with bronze hair and skin. His appearance is compared to a bronze statue of Apollo, who is coincidentally the god of music, art and poetry, befitting of a tutor.
His near-faultless appearance attracts many female admirers; when he marries Nubia, several girls and women are very disappointed.


  • Aristo is a male given name of Greek origin and means 'best'.
