Here’s a random thought for graduate work in some discipline that probably doesn’t exist (some combination of art history, literature, sociology, psychology, folklore, maybe comparative religions, but hey, let’s just say History because that’s what I did my undergraduate degree in because I couldn’t pick any single one of the above (or because I think most of those fields are flawed or have too many limiting assumptions to be fields of serious study)).
Many if not most cultures have stories and artistic depictions of giants. Most of the depictions of giants I can think of have humans coming up to right below the knee. Is that true? Are the sizes of the giants in proportion to average human height constant over time and cuture? If they vary does that tell us something about the culture or time? Where do giants come from? Is it because we all viscerally remember being children and having to navigate a world of terrifying giants, whose strange rules you need to learn to survive?
