No. 1. That Bronze-casting spread from a common centre by conquest or migration.
No. 2. That each region discovered the art independently, and made its own implements.
No. 3. That the art was discovered and implements were made in one spot, whence commerce disseminated them.
No. 4. That the art was diffused from a common centre, but that the implements were constructed in the countries where they were found.
No. 1. Characterised by flat or slight flanged celts and knife-daggers, found in barrows with stone implements.
No. 2. Age of heavy dagger-blades, flanged celts and tanged spear-heads, such as those from Arreton Down. In these two the Sword is unknown.
No. 3. Palstaves, socketed celts (introduced from abroad); true socketed spear-heads, Swords, and the variety of tools and weapons found in the hoards of the old bronze-founders.
And a great peculiarity in Britain is the absence of nearly all traces of the Later Bronze Period in graves and barrows.
