Where did Shakespeare get his idea from?

Shakespeare got his ideas from a wide range of sources, including classical literature, history, folklore, and his own life experiences. He was particularly influenced by the works of ancient Greek and Roman dramatists, such as Sophocles, Euripides, and Plautus. He also drew inspiration from the Bible, medieval romances, Italian Renaissance literature, and the works of his contemporary playwrights, such as Christopher Marlowe. In addition, Shakespeare was an avid observer of human nature and society, and he often used his own experiences and observations as material for his plays.
