What do Jesus, da Vinci, Michelangelo, Shakespeare, Beethoven, St. Francis, and Copernicus have in common in A Wrinkle in Time?
All these historical figures are examples of Earthlings who, according to Mrs. Whatsit, Mrs. Which, and Mrs. Who, fight the Black Thing. Mrs. Whatsit, Mrs. Which, and Mrs. Who explain that the Black Thing tries to take over planets, including Earth. Meg has already identified it as a concentrated form of pure evil, when she and Calvin and Charles Wallace viewed it from Uriel, on the back of Mrs. Whatsit. Having now tessered through it and felts its power and with the knowledge that her father is in its clutches, Meg despairs of him escaping. The act of identifying the philosophers, mathematicians, artists, and other great figures of culture and history who have helped fight it off with their creativity and innovation helps to inspired Meg to believe that the Black Thing can be beaten.
