Turns out the Metropolitan Museum of Art was ill-prepared for the likes of 13-year-old Benjamin Lerman Coady, who has corrected a map on display in the museum's Byzantine Gallery, reported The Hartford Courant.
The item in question, a map displaying the empire at its height in the 6th century and part of the museum's permanent Byzantine collection, neglected to show Spain and part of Africa, according to the Courant.

The seventh-grader was invited back to the New York museum for a personal meeting with Evans, who says the museum will update the map, reported the Courant.
All thanks to one smart kid.
