Nobody knows what the figure means, or even quite what it is -- a horse? a dragon? -- but it appears to be from the Iron Age or possibly the earlier Bronze Age, and is associated with the nearby hill fort site. The shape of the figure seems to have changed over time, and there is uncertainty as to what it originally looked like.

Some say it's a horse, a tribute to the Celtic goddess Epona. Some say King Alfred had it cut to commemorate his victories. Some say George slew the dragon on nearby Dragon Hill and it has to do with that. The fact is, nobody know what the heck it is, how old it is, or what it meant.
What we see on the Greenwood Tarot card is the 'head' of the horse, apparently snorting golden plumes of the 'breath of life'.
The card is the Ace of Arrows, or Ace of Swords -- a card of clear thinking. It is decisive ability, cutting through confusion or illusion, making a radical decision, seeing through deception, etc. The card focuses on the eye of White Horse of Uffington, and the arrow aligns with its upright ears. The horse has come alive with alertness and snorts in response to what it sees or understands.
It's an interesting card, but hard to apply to today, which as far as I know will be an easygoing day off. I do have a dentist appointment at 9.10 this morning, and will HOPEFULLY get this tooth fixed for good and ever.
