After invading Achaemenid Persia in 330 BC, Alexander the Great sent the main force of his army to Persepolis by the Royal Road. Diodorus Siculus writes that on his way to the city, Alexander and his army were met by 800 Greek artisans who had been captured by the Persians. Most were elderly and suffered some form of mutilation, such as a missing hand or foot. They explained to Alexander the Persians wanted to take advantage of their skills in the city but handicapped them so they could not easily escape. Alexander and his staff were disturbed by the story and provided the artisans with clothing and provisions before continuing on to the Persepolis. Diodorus does not cite this as a reason for the destruction of Persepolis, but it is possible Alexander started to the see the city in a negative light after the encounter.
