An early, extensive list of “angling virtues” is provided by Gervase Markham:
. . . a skilful angler ought to be a general scoller, and seen in all the Liberal Sciences, as a Grammarian to know how either to write or discourse of his art in true and fitting terms, either without affectation or rudeness. He should have sweetness of speech, to perswade and entice others to delight in an exercise so much laudable. He should have strength of arguments to defend and maintain his profession, against envy or slander.
He should have knowledge in the Sun, Moon, and Stars, that by their aspects he may guess the seasonableness or unseasonableness of the weather, the breeding of storms, and from what coast the winds are delivered. He should be a good knower of countries, and well used to High-wayes, that by taking the readiest paths to every Lake, Brook and River, his Journies may be more certain and less wearisome. He should have knowledge in proportions of all sorts, whether Circular, Square, or Diametrical, that when he shall be questioned of his diurnal progresses, he may give a Geographical description of the angles and channels of Rivers, how they fall from their heads, and what compasses they fetch in their several windings. He must also have the perfect art of numbering. . . .
