X is Satyajit Ray's 1980 short film Pikoo, based on a story from his book. It shows a day in the life of a six-year-old boy against the backdrop of his mother's extramarital affair. Ray was approached by a French producer to make the film. Only black-and-white photographs exist of Diego Rivera's controversial mural Man at the Crossroads, which was destroyed before completion due to its depiction of Lenin. Socrates, Plato, and Aristotle are connected in the lineage of Greek philosophers, with Alexander coming next.
