I originally created this collection by hand once in Minecraft 1.8.9 and then later reused it for a 1.12.2 project.
I created it as a brainstorming map to see what statues I could think of and be possible with only a minimum of blocks of stone in only one chunk.
Every statue is in one chunk for easy copy and paste.

Maybe you can use it for a datapack or for a mod/plugin or just to distribute a little more statues in your world or on your server.

Have fun.
