So, I did a quick image search for Rosslyn Chapel maize and corn (see sibling comment), and I found nothing that looked convincingly like corn to me. There were a few things that looked a little like corn, but I would interpret them as other plants and/or bread.

They pretty clearly look like sheaves of wheat to me, to the extent that it wouldn't have occurred to me they might be something else.
