[VFB] What's an Angle?

[StevenOjai]

I'm wondering about the term "Angle"....Dame Berners (1496) wrote "A treatyse of fysshyng with an angle"; P. Fisher (1835) wrote "The Angler's Souvenir"; and Eric Travener (1933) wrote "Trout Fishing from all Angles", etc. I've associated the term with using a bait or lure to entice fish to bite a hook but how did this use of the term come about.?? We've become known as "Anglers" as a result of the use of this term.
Why did Dame Berners use the term in 1496? What was her angle??
OK, O' DonO, the perveyor of all knowledge with regard to fly fishing, whom also dated Dame Berners and taught her everything she knew....Put on your Johnny Carson, 'Swami Hat', and tell us o'learned one.
