Who was the first inventor of guitar?

The exact origins of the guitar are shrouded in the mists of time, but the earliest known stringed instruments similar to the guitar appeared in ancient Mesopotamia, Egypt and India. The modern guitar, however, is generally considered to have evolved from the vihuela, a guitar-like instrument that originated in Spain in the 15th century. The modern classical guitar, with its six strings, is attributed to the Spanish luthier Antonio de Torres Jurado, who introduced several important design changes in the 19th century.
