Around 500 years later, King Angus of the Picts, facing a large army of Saxons at Athelstaneford in what is now East Lothian in Scotland, was overwhelmed by a blinding light the night before the battle and, during the night, had a dream. The message he was given was that he would see a Cross in the sky and would conquer his enemies in its name.
The following morning King Angus looked into the rising sun and saw the Saltire Cross in its blinding light. This filled him and his men with great confidence and they were victorious.
From that time Saint Andrew and his Saltire Cross were adopted as the national symbols for an emerging Scotland.
The Saltire Cross became the heraldic arms that every Scot is entitled to fly and wear. However, its colour was not white at first but silver (Argent), as in heraldry white stands for silver.
Both William Wallace and King Robert the Bruce appealed to Saint Andrew to guide them in times of national emergency.
The Saltire was flown on Scottish ships and used as the logo of Scottish banks, on Scottish coins and seals and displayed at the funerals of Scottish kings and queens - that of King James VI for example and of his mother, Mary Queen of Scots.
When King George IV visited Edinburgh in 1822, he was presented with a Saltire Cross made of pearls on velvet, within a circle of gold.
There are also broader connections. Saint Andrew and his relics at St Mary's Metropolitan Cathedral, Edinburgh provides Scots with a special link to Amalfi in Italy and Patras in Greece (where two Cathedrals named after the saint also hold his relics).
The many St Andrew's Societies worldwide, set up originally as self-help organisations for Scots who had fallen on hard times, form a network of Scots who are all united under the Saltire Cross of Saint Andrew. They give Scotland a European and worldwide dimension.
