Final answer:
Washington Irving’s inspiration for 'The Devil and Tom Walker' came from his interest in the supernatural, American folklore, and his readings, including Cotton Mather’s work.
Step-by-step explanation:
Washington Irving was inspired to write The Devil and Tom Walker by his fascination with the supernatural and American folklore. His interactions with various tales of the occult, the influences of his readings such as Cotton Mather's writings, and the local legends surrounding the areas he lived in or visited, all fed into the creation of his story. The dark, enchanting atmospheres described in his works, such as The Legend of Sleepy Hollow and the eerie nature of the settings he chose, like the Tappan Zee and Sleepy Hollow itself, reflect this deep interest in the mystical and the macabre which inspired Irving's writings.
