MADRID - Scientists on Monday launched a radar-assisted hunt in a Madrid convent for the remains of Spanish writer Miguel de Cervantes, author of “Don Quixote”. Two technicians in grey vests paced around a church altar in central Madrid’s red-brick Convent of Trinitarians, sweeping a ground-penetrating radar in search of the body of the writer. The radar revealed images of what lies beneath the floor, the start of the first significant search for the remains of a writer who died in poverty on April 22, 1616, despite creating one of the landmarks of Western literature.
