The eye

The eye of the PRE should be clear, dark, big, happy, steady, forward looking and with long thick eyelashes and they should have a triangular/ almond-shape (see below). The eye should not be too close to the base of the ears as it makes the forehead look too large.
Sometimes you can see what seems to be hard wart over both eyes of the foal (see below), these are not warts but in fact horn-embryos. Some say the original pure spanish horse had horns and that this is a sign of purity.
"The unicorn is the only fabulous beast that does not seem to have been conceived out of human fears. In even the earliest references he is fierce yet good, selfless yet solitary, but always mysteriously beautiful. He could be captured only by unfair means, and his single horn was said to neutralize poison."

Every animal has their objective qualities, to me a horse represents goodness, a uncorruptive mind, beauty, natural simplicity, to be present and freedom of spirit.
