Here's an aspect of Mercury I don't think I've really discussed before (other than drooling over the statue of Him). Then again, I'm almost at the 300 post mark, so really, I don't recall everything I've posted about in the past 9 months. As the ruler of communication and commerce it only makes sense that travel is also within his domain: Messages travel from one person and/or place to another, goods must travel to get from farm to market or workshop abroad.
Here is a spell I was given. A friend and I parted ways in the city today. For me it was a quick jaunt to my abode, but he had a long trip ahead so this came to mind. It can be done for yourself or another, using me/my or person's name/their.
Mercury, Lord of Air and Sky
make my long trip hurry by.
Make my travel smooth and sweet.
As swiftly as your winged feet
Carry you from throne to land,
Over sea, across the sand
to destinations fair and bright,
Mercury, gently alight
me safe and sound
back to my home where I am bound.
Mercury, as I am true
Do now what I ask of you
My word you have,
to honor you.
When you get home, tip an offering. Coins, incense, food, etc.
Of related Mercurial interest: I was just looking up something Ovid had written and came across a picture of a vase where Mercury is wearing the cap of Adoneus (aka Hades). I haven't found other references to the helm of invisibility being part of His travel retinue. Some say it's the same as his messenger cap, other sources say it's different, ie: Perseus returns all of the things he was loaned by the Gods to Mercury, including the Black Helm. Interesting point of conflicting lore. It seems minor, but nothing about Mercury is minor. ;)
