By my calculations, If the Roman Empire had railroads, people would have landed on the Moon by 1820. This is an actual railway spike. These things are made from carbon steel, and used to fasten the train tracks to the wooden railway ties. I carved the end of this one using diamonds and water. The design is classical, and incorporates latin scripture. “ Ferrum Via Rex Rgis”, the English translation is, "King of the Railroad".
