If the surface is occluded by the Moon, prominences are visible to the naked eye. Outside of rather exotic optical systems, there is no way to block the surface of the Sun from the ground well enough to see prominences, so the only way pre-technological people would have seen prominences would have been during total solar eclipses. We see prominence images made through narrow band filters, typically H-alpha, where the prominence is bright compared with the surface (or more accurately, nearly all of the prominence light is passed, and nearly all of the surface light is blocked).
