Drawings of Birdman image engraved on a shell cup from the Spiro site (top) and a Ripley Engraved bowl with pendant triangle scroll (bottom). Scalloped elements depict downy feathers. It is easy to see scalloping on Birdman, on the upper part of the wings with the long feathers hanging down below. To see scalloping on the scroll, you have to focus not on the dark pendant triangles but on the empty spaces between them. |
