Question

Which is the letter of the alphabet that was not used? Using the scale in the map, measure the length of any one of the small squares.

Answer 1

1. The letter of the alphabet that was not used is the letter “I”; it was deliberately skipped and not used to divide the site grid. In cartography and archaeological surveys, “I” is excluded to avoid visual confusion with the number 1 or the letter J.
2. According to the survey documentation accompanying the map, the initial large grid divides the vast city into 25 squares. The length of each major square side represents 1 kilometre on the ground, while the next layer of subdivided smaller units measures exactly 100 meters per square side.
