I've been doing a little bit more research.
(a) How do birds fly/bird flight mechanics. Mort specifically, wing shapes & why, speed... I found the bit about the Peregrine falcon. When it's diving, it reachs that 200+ mph speed. But what about when it's just flying around? I read somewhere that messenger pigeons could fly 60mph.
(b) Ancient and Medieval underwear. There is very little known about it. Most of it is speculation. So, I'll stick to learning what it was made of. Linen & wool mostly. Sounds so comfortable, doesn't it?
Actually, I would need to brush up on the clothing notes I have somewhere.
Clothing's not always practical, and some of it wasn't anymore practical then than it is now. Unless they're a peasant or poor. Then you make practical with what you got.
This WiP takes place during the summer. Personally, I don't know how summers are in other places. Here in Mississippi, summer starts in May/June and doesn't end until Christmas. Yes, January through March are pure bliss. Sometimes we're lucky and it gets cold a little bit sooner.
How awful would it be for a psuedo-medieval prince to just wear some modern-day-looking shorts and sandals? Oh yeah, and a sleeveless shirt?
Next on the list:
How the early printing presses worked. This has been drilled into me for the past few years in school, both high and college. I want a little more information.
Will any of this actually make an appearance in any of my books?
Probably not. But I want to know. I like to have a clue at least of what I'm trying to write about, or even if I can pull it off my whichever world I'm working on.
