Javelins have been around for at least 400,000 years.
That's longer than there have been people.
The 400,000 year-old ones found in Germany are made of spruce and would have been used by either Homo erectus:

A javelin is designed to go far and fast, and javelins have given their name to various aircraft, plane engines, rockets, trains, cars, coaches, phones, racing dinghies and phones.
There's also a Javelin frog:
a Javelin sand boa:
a Javelin fish:

Spot the frippet: javelin. This word comes from the Old French word javeline, which is a version of javelot, which is Celtic.
