There are a lot of stories with characters, places, or events which represent the seven deadly sins, the signs of the zodiac, or the muses of Greek mythology. If you want a motif that hasn’t been done to death, but isn’t impossibly obscure, here are some suggestions.
Note: a motif can be a single thing as well. These are for if you want a motif including several different objects.
- The four gospel authors (one of the few relatively unused biblical motifs)
- Extant plays of Sophocles
- The Orishas
- Galaxies in the Local Group
- Similarly, groups in the Virgo Supercluster
- Geologic eras and periods
- Chapters ofThe Art of War
- Fur, feathers, scales, and skin
- Legendary swords from various stories/cultures
