In Shakespeare's play The Tempest, what was Gonzalo's role in the overthrow of Prospero, besides giving Prospero and his daughter food?
He had no involvement. Shakespeare implies that Gonzalo was the only honest subject surrounding Prospero. He had no plans to gain power or gain any advantage from usurping Prospero's position. It seems like he's just a really good friend who couldn't stop what Prospero's brothers were doing, so he tried to help them as best he could.
