The Musket is a type of firearm that typically featured a long, smoothbore barrel and fired either a musket ball or (from the 1840's) a Minie ball. The Musket was heavily developed during its 4 centuries of use from the 1400's to the late 1800's, with different types of muskets evolving.
The crossbow was invented in Ancient China during the Zhou dynasty, around the year 700 BC. A Chinese text, from about 200 BC, gives credit to a Mr. Ch'in of Ch'u for inventing the crossbow.
