Chaucer began writing The Canterbury Tales probably around 1387. Its first printed version came with William Caxton’s introduction of the printing press in the late 1470s. Chaucer wrote the Treatise on the Astrolabe for his eleven-year-old son in 1391. According to the inscription on his tomb, Chaucer died on October 25, 1400, and was buried in Westminster Abbey in London. His remains were moved to the Poets’ Corner in 1556 and he was the first writer to be buried there.
