Hi Kate. I looked in Nicholas Moore's "Spode Greek" and didn't find this image there either, though there were some of the Greek patterns with the same red and black coloring. Search in Google Images for "The Horses of the Morning" by Flaxman and you will see this same image (with accompanying figures) which either pictures Aurora, or Eos, Goddess of Dawn, or her sister Selene, Goddess of the Moon (the sources were a little unclear). But this image was by William Flaxman, the same artist on whose prints the rest of the Greek series was based.
