Hey Gath... who cares about your 'context'? This isn't literalville.com Sir. If you can't appreciate humor then trust me, compensating by denigrating the accomplishments of others is a sure sign that you have a 'context' problem. Just sayin'.
The Saga of Hrolf Kraki features a shoreline battle between Viking tribes, in which a king and his best archer "fire" arrows from a boat offshore at the enemy. Loose may have been an early Old English term, but it wasn't and isn't the only correct one.
One does not "fire" an arrow in this context. One Looses an arrow. If wished to fire an arrow it would be wrapped with a combustible near the base of the arrowhead, and passed through a flame. Just sayin'.
