There are two other big factors: weather and the availability of poisons. In a rain forest (or on the water) bows tend to either rot or warp (think about wet wood), so in such an environment, you're stuck with some version of a big wood bow, ideally with no knots. Those palm-wood Papuan bows are a good example. In somewhat drier environments, you can start adding backings (sinew, horn, bamboo, etc) to improve the spring, creating many variations on the compound bow. This was done all over the northern hemisphere, from the Arctic (cable backed bows) to Turkey, Korea, China, California, etc. This is an ideal solution if you're living in an area where good bow-woods are scarce but there are big ungulates to provide the other material. It's also not a bad solution if you want to beef up a big wood bow. Backings tend to be glued on, and glues can go bad in wet weather, so there's a trade-off between power and versatility/durability. Small compound bows are useful for horseback, and are the classic solution adopted by the steppes nomads, all the cultures they contacted, and the Plains Indians. Small and powerful, they are also fussy, need a fair amount of care, and can be inaccurate (due to the small arm length). As for poisons, they seem to be used where available. For example, some northern California tribes used small sinew-backed bows capable of taking a deer on power alone. They also poisoned their tips with rattlesnake venom. The ancient Greeks reputedly poisoned their arrows, as did the Ainu when they were hunting bears with them. The Kalahari bushmen have a crappy environment for bow woods and few tools to work them, but they have some excellent toxins, so they use light bows with tiny needle-like poisoned arrows, and kill with those. The west African tribes such as the Tiv reportedly use a mix of Calabar bean and whatever snake venom they can get their hands on, and build normal wood bows but use prickly arrowheads to get the poison in. And so forth. Thing is, bows and arrows aren't simple. Their design takes into account the local environment, materials available, and intended use, and a lot of clever bowyers have independently come up with similar solutions for thousands of years.

The English longbow is one of the bows optimised for maximum energy, which is very important for armour penetration. Most game animals don't wear armour, so not such a big deal for hunting bows. Some of the stone/iron age European bows are large, probably moderate draw weight (i.e., pretty high draw weight for us moderns), and inefficient. Inefficient is a Bad Thing in modern archery, since it robs you of speed, and thus of flat trajectory. But if you're a hunter who has to make his own arrows, low velocity is not always a bad thing - it's easier to find you arrows when you miss. For a self bow, starting from scratch, I find it's easier to make the bow than the arrows. Losing/breaking arrows is a largely ignored disadvantage of powerful and efficient bows. As you say, it isn't simple. The optimisations for warfare, hunting, and sporting archery are all different. That's not even looking at the different types of warfare, hunting, and sport! We can add ritual archery to the list, too. |
