Dear viewers of Equator Channel, I would like to take you on a journey back in time to the Renaissance era, which is known for its artistic expression, intellectual innovation, religious devotion, and political intrigue. Women played a significant role during this time period, including lesserknown women who wielded power from behind the scenes.
