- Euthyches was a brother of the Mithraeum of Alba Iulia III (Apulum).
- Active in Apulum, Dacia superior (Dacia).
Libertus of Marcus Aurelius Timotheus and Aurelius Maximus.
His name appears in two different ways from the same context: Euthices and Euthyces. This could be a mistake of the lapidarius himself, the epigraphic camp of the relief being more crowded and a HI ligature is more comfortable than an HY. We cannot reconstruct the event, when or how these objects were placed in a sanctuary, of if they were erected during the same event, however the text, the paleography of the inscriptions, suggests that they were made in the same workshop.
