How long was Bruno jailed and tortured

The answer is 7 years

If you are talking about Giordano Bruno, you need this answer.

When Bruno announced his plan to leave Venice to his host, the latter, who was unhappy with the teachings he had received and had apparently come to dislike Bruno, denounced him to the Venetian Inquisition, which had Bruno arrested on 22 May 1592. Bruno defended himself skillfully, stressing the philosophical character of some of his positions, denying others and admitting that he had had doubts on some matters of dogma. The Roman Inquisition, however, asked for his transfer to Rome. After several months of argument, the Venetian authorities reluctantly consented and Bruno was sent to Rome in February 1593.
