Cannon [SEP] Introduction
The word "cannon" can be both singular and plural. The earliest known depiction of cannon appeared in Song dynasty China as early as the 12th century; however, solid archaeological and documentary evidence of cannon do not appear until the 13th century. In 1288 Yuan dynasty troops are recorded to have used hand cannon in combat, and the earliest extant cannon bearing a date of production comes from the same period. By the early 14th century, depictions of cannon had appeared in the Middle East and Europe, and almost immediately recorded usage of cannon began appearing. By the end of the 14th century cannon were widespread throughout Eurasia.
