The quote "all greatness must first take its shape in dreams" from Jean Plaidy's "The Borgias: Two Novels in One Volume" emphasizes the importance of imagination and vision in achieving significant accomplishments. It suggests that every great achievement begins as an idea or dream, reflecting the necessity of creativity and aspiration in the journey toward success.

This perspective reminds us that before any monumental acts or milestones can be realized, they must first exist in the mind. Dreams serve as the foundation for ambition, motivating individuals to pursue their goals and turn their visions into reality, which is especially relevant in the historical context of the Borgia family and their influential legacy.
