Miguel de Cervantes' Don Quixote is often hailed as the first modern novel, a brilliant blend of comedy, tragedy, and philosophical reflection. It follows the adventures of Alonso Quixano, a nobleman who, obsessed with tales of chivalry, renames himself Don Quixote and sets out to revive knight-errantry. Accompanied by his loyal squire Sancho Panza, he tilts at windmills, rescues imaginary maidens, and confronts the gap between illusion and reality. The novel works on many levels: as a parody of medieval romances, as a profound meditation on dreams and disillusionment, and as a timeless study of friendship. Cervantes balances satire with tenderness, inviting readers to laugh at Don Quixote's folly while admiring his unyielding idealism. More than four centuries after its publication, the book endures as a universal story about hope, madness, and the stubborn human pursuit of meaning.
