Back in 1536 or so, in Saint-Pourcain France, two students met in University de France alchemy class. One was Blaise de Vigenere and the other was an aristocratic kid named Count Cristoff Von Carbon. While in the lab one day, they had some free time and started working on a formula to convert lead into gold. They tried all kinds of things. Lead and sulphur melted together to give lead a gold color. Didn't work. Tried adding lye (NaOH) and salt (NaCl). Nothing seemed to work at first. But after much trial and error, they actually succeeded. To safeguard their formula, they decided to encrypt the coordinates of the hiding place. (Of course....Why not.) Blaise wanted to use a cipher. The Count agreed but wanted a little more security. He added a second tier to the cipher involving one of the "Six Building Blocks of Life". Both being chemists, they agreed and came up with this combination code:

So that they would not forget what the code key was they decided that the key would be the last name of their Greek Language teacher.Solve this puzzle and retrieve the cache. Who knows, you might find the formula for turning lead into gold.......Or not.
