Duck-Driven Chariot

I was reading a book on Norse mythology that was written in the 60s (cracking up over it, I might add) when I came across a description of "sun disks on boats or chariots, often driven by water birds such as ducks, geese, or occasionally swans." I loved the image despite it's being complete BS and decided to draw it. Here ya go!

The duck is actually a Swedish Black Duck or something like that.
