Gezelius was a peasant"s son from Västmanland, but was observed in childhood to have apparent gifts and was given a personal tutor, Boetius Murenius. His first professorship was in Greek and oriental languages at the Dorpat university in 1642. In 1666 Gezelius published En rätt barnaklenodium, which went through 70 editions over the next two centuries.
In 1672 Gezelius published a three-piece Latin encyclopaedia, (Encyclopaedia synoptica: ex optimis & accuratissimis philosophorum scriptis collecta), which specifically dealt with fields of philosophy and mathematics.
Encyclopaedia synoptica is considered to be Finland"s first encyclopedic work.
