In a letter which he wrote to Buxtorf from Mantua on November 6, 1637, Gai declared that he had emigrated to Botzen, a town in the South Tyrol, where he had become the tutor of the two sons of a rich man named Jacob Moravia.
He studied German at Botzen, and after a stay of five years and a half returned to Mantua.
Attributing the translation to Buxtorf the Elder, Gai wrote a letter expressing admiration for the father.
Buxtorf explained to Gai that he himself was the translator, and sent him a copy of his dissertation "Diatribe" as a present.
