About this design
It is said by many that Claudius Aelianus first recorded the use of an artificial fly, cast with a rod and line, by Macedonian fisherman on the Astraeus River.
...they have planned a snare for the fish, and get the better of them by their fisherman's craft. . . . They fasten red . . . wool round a hook, and fit on to the wool two feathers which grow under a cock's wattles, and which in color are like wax. Their rod is six feet long, and their line is the same length. Then they throw their snare, and the fish, attracted and maddened by the color, comes straight at it, thinking from the pretty sight to gain a dainty mouthful; when, however, it opens its jaws, it is caught by the hook, and enjoys a bitter repast, a captive.
Since then, little has changed, it seems. Technology may have been refined, along with the manufacture of the 'fly ', but it essentially remains the same today as it has done for the better part of two thousand years and probably more. Some things, i suppose, are invented the best that they can be right from the start.
