Three Suns and Mortimers Cross




Three glorious suns, each one a perfect sun;
Not separated with the racking clouds,
But sever'd in a pale clear-shining sky.
See, see! they join, embrace, and seem to kiss,
As if they vow'd some league inviolable:
Now are they but one lamp, one light, one sun.
In this the heaven figures some event.

William Shakespeare Act Two Scene One of Henry VI, Part 3:

On the morning of February 2nd 1461, in the county of Herefordshire, two armies prepared to face in battle.   For six years, the Yorkist and Lancastrian forces had battled for the English crown and this was to be the next major installment.  The Yorkist army was now led by the 18 year old Edward, Duke of York. The Welsh Lancastrian armies of Sir Owen Tudor and other nobles loyal to King Henry VI were attempting to meet with the other supporting forces in England. The battle was a key event in continuing the separation of the Lancastrian armies and defeat for the Yorkists would have been a calamity for their cause.   

On the dawn of battle, a rare an unusual celestial phenomenon occurred, a parhelion or ‘sun dog’. The sun appeared to be split into three, rising over the horizon in unity. This was taken by the Yorkist men as an ill omen until Edward convinced them that it was a positive sign from heaven, the holy trinity and possibly representing the three sons of the Duke of York who were present in the army.
At Tretower court in the south of Wales, there is a replica tapestry depicting the event.

The Battle was decisive in the Yorkists favour , Sir Owen Tudor was captured and put to death while the Lancastrian forces were severely weakened and dispersed.

The phenomenon occurs when light is refracted off plate-shaped ice crystals high in the upper atmosphere- one of many halo effects- and can occur anywhere on the planet with the right conditions present. Very cold weather and cirrus or cirrostratus clouds at the same time.   
 
The overall appearance is one where the sun appears to have two fainter counterparts each side and exactly 22ยบ apart, there are also two further that appear much fainter above and below the sun and the whole array is made up of a circular design that has a variable level of clarity, dependent on the conditions. The best appearances occur when the sun is both close to the horizon and during the winter months.
