From the Fountain Tarot, the Knight of Coins; from the Devas of Creation, "Mercury:"
Not too long ago I came across an article on the web about a French postman who started collecting unusual pebbles and rocks on his daily route. He decided to build a castle with them and spent the next thirty-three years creating an extraordinary example of naive art architecture. Cheval (the postman) was definitely a Knight of Coins kind of guy, a person who achieves success through dogged determination and dedication. The Fountain booklet's phrase for this card is "methodical victories." Passion that burns out after a few days won't get you far. This guy might move like a tortoise but at least he'll finish the race.
Mercury is the smallest planet in our solar system. Being the closest to the Sun, it also makes the fastest orbit. It is named for the Roman deity Mercury, the messenger of the gods. This Deva's message is twofold. See how that knight is loitering under the arch? Mercury gives a prod to keep him from becoming so focused on details that he stops moving. Additionally, Mercury's role of messenger suggests that it might be a good idea to communicate and get feedback from others. Slow and steady is fine, just don't grind to a halt or isolate from others.
