invecked

The crooked Lines are these following : The first two Lines, Plate II. named ingraled and invecked, when represented together, are somewhat known, the one from the other, being opposite to one another, both being made (as it were) of Semicircles; the ingraled with Points upward, and the invecked Line with Points downward. But this is not yet a sufficient Distinction: For, suppose the Space betwixt them, which they form, be a Fess, then it's only ingraled, and not invecked; for a Fess ingraled, must have the Points on both Sides turned twoards the Field, and the convex or gibbose Parts towards the Fess it self; and so of a Bend, Chiveron, and other proper Figures in Herauldry: And if these be invecked, then the convex Parts of the Line are towards the Field; [...] within a Bordure invecked. These two Lines, ingraled and invecked, are more hard to be distinguished, when the field is divided into two equal Parts of different Tinctures, [...] Here we know not whether the Line be ingraled or invecked, except we observe this Rule, That the Form of the Line must be applied to the Colour first named. The French, for ingraled, say engrele; and for invecked, canele:
