What is the origin of the question mark?
Question mark
late 8th century
Lynne Truss attributes an early form of the modern question mark in western language to Alcuin of
 York.[2] Truss describes the punctus interrogativus of the late 8th century as, "a lightning flash, striking from right to left".[3] (The punctuation system of Aelius Donatus, current through the Early Middle Ages, used only simple dots at various heights.)
