English: Hand cannon for a knight, called a petronel, from a manuscript in the ancient library of Burgundy. The articulated plate armour is characteristic of the latter half of the fifteenth century, though the bassinet has a movable vizor. These hand cannons were in use at the same time as the serpentine arquebuse, and even as the flint and steel arquebuses and muskets, i.e. till the beginning of the sixteenth century, as may be seen from the drawings, by Glockenthon, of the arms of the Emperor Maximilian I. (1505).
