In principle, the crossbow is a horizontally mounted bow on a centre column, that permits the archer to keep the weapon loaded without requiring much effort as it has a load-holding device, meaning that the archer can easily aim and fire precisely.
By using a suitable construction the crossbow can store far more energy and transfer it to a projectile than an archer using only his own arm power possible could.
