Ah, stags and antlers. You might be interested then in a recent discovery I made on another thread..

Hart (deer) https://en.wikipedia.org/wiki/Hart_(deer)

Hart is an archaic word for "stag"... Specifically, "hart" was used in medieval times to describe a red deer stag more than five years old.

In medieval hunting terms, a stag in its first year was called a "calf" or "calfe", in its second a "brocket", in its third a "spayed", "spade", or "spayard", in its fourth a "staggerd" or "staggard", and in its fifth a "stag", or a "great stag".[1][2] To be a "hart" was its fully mature state. A lord would want to hunt not just any deer, but a mature stag in good condition, partly for the extra meat and fat it would carry, but also for prestige. Hence a hart could be designated "a hart of grease", (a fat stag), "a hart of ten", (a stag with ten points on its antlers) or "a royal hart" (a stag which had been hunted by a royal personage).[3][4] A stag which was old enough to be hunted was called a "warrantable" stag.

Hart in medieval hunting https://en.wikipedia.org/wiki/Medieval_hunting#Hart

The king of all the wild animals was the deer, and more precisely the hart, which is an adult male of the red deer. The hart was classified by the number of tines, or points, on its antlers. An animal should have at least ten tines to be considered worthy of hunting; this was referred to as a "hart of ten."[3] Deer could be hunted in two different ways: par force ("by strength" and hereunder par force de chiens ("by force of dogs" )), and bow and stable.

The hart was a highly respected animal, and had great symbolic and mythological significance. It was often compared to Christ for its suffering; a well-known story tells of how St. Eustace was converted to Christianity by seeing a crucifix between the antlers of a stag while hunting. A similar story is attributed to St. Hubert. Other stories told of how the hart could become several hundred years old, and how a bone in the middle of its heart prevented it from dying of fear.

So, think now to the Christ story. Think of the images of Christ with the sacred heart.. If the stag is an ancient symbol of Christ and is the King of animals to be hunted with the antlers as a token of the successful hunt, is it any wonder that antlers are so symbolic for satanists?

Red deers and stags are a feature of Bushy Park, London and I've been meaning to do a post about this area. But briefly:

The park was created in the early 16th century to provide a hunting ground for Hampton Court and the Longford river was cut across the park in the late 1630s to provide the palace with fresh water. Sir Christopher Wren created Chestnut Avenue as a formal approach to Hampton Court Palace, with the Arethusa, or Diana, fountain as its centrepiece.

There's a minefield of a story in that little paragraph.. but for another time..

After the Norman invasion of 1066, Hampton was passed to Walter de St Val�ry. His descendants transferred it to a London merchant, Henry de St Albans, who sold it in 1237 to the Knights Hospitaller of St John of Jerusalem. The Order already owned a house on the site of today�s Hampton Court Palace, and the neighbouring Manor of Hampton was purchased to employ new land management techniques designed to maximise the profit necessary to fund their overseas exploits.

During the Commonwealth period, Bushy Park narrowly escaped break-up thanks to Oliver Cromwell who was living at Hampton Court Palace by the courtesy of Parliament. In 1652 the park was bought by a property consortium led by Edward Backwell, a Goldsmith of London. Next year Cromwell, now proclaimed Lord Protector of England, sought to reclaim the Park so that it could be re-joined with the Palace. There was hard bargaining and he only achieved this in 1654, and at a premium.

There are currently about 320 deer and their grazing is essential to maintain the high wildlife value of the park's grasslands.

Cromwell lived at Hampton Court Palace which is very close to Eel Pie Island and is located in a park [Bushy Park] which 'extends to approximately 1100 acres.

Prior to Cromwell:

That's the Knights of Malta....
