A big part of the reason for Caesar’s success was a group of german mercenaries he hired. They were not just big men. Their fighting spirit was frightening to all they encountered.
In battle they were like the Viking Berserkers who were known for taking drugs to get them crazy for battle. The Caesar’s Germans may have done the same.
Berserkers, exactly, that was my first thought too. Those spoons may have been sized for the right amount of one certain kind of plant, which could vary depending on the plant, or also on the size and sensitivity of the warrior.
I have a good friend who grows his own (in a legal state). As a senior citizen he has spinal arthritis which acts up from time to time. He processes the weed, soaks it in grain alcohol, which prepares a tincture. Three or 4 drops can kill the back pain and put him in a good mood. One day I was visiting and he was out for several hours. I decided to fix a treat with 2 servings. I used 1/4 teaspoon of his vanilla to make the pudding and ate my cupful. Soon I was feeling very strange and began to wonder if I was having a stroke. I did not want to try driving to a hospital, so lay down to wait for him, and dozed off. He returned hours later. I woke up feeling better and told him my bad experience. I mentioned using his vanilla and he burst out laughing, “that bottle is my tincture, that other bottle is vanilla.” So, 1/8th teaspoon, wow!!
