Why Henry VIII. substituted the harp for the three crowns is not really known. Some would have us believe that the king was apprehensive that the three crowns might be taken as symbolising the triple crown of the Pope; while others suggest that Henry, being presented by the Pope with the supposed harp of Brian Boru, was induced to change the arms of Ireland by placing on her coins the representation of this relic of her most celebrated native king. The Earl of Northampton, writing in the reign of James I., suggests yet a third explanation. "The best reason," saith he, "that I can observe for the bearing thereof is, it resembles that country in being such an instrument that it requires more cost to keep it in tune than it is worth."[20] {34} The Royal Standard should only be hoisted when the Sovereign or some member of the royal family is actually within the palace or castle, or at the saluting point, or on board the vessel where we see it flying, though this rule is by no means observed in practice. The only exception really permitted to this is that on certain royal anniversaries it is hoisted at some few fortresses at home and abroad that are specified in the Queen's Regulations. The Royal Standard of England was, we have seen, in its earliest form a scarlet flag, having three golden lions upon it, and it was so borne by Richard I., John, Henry III., Edward I., and Edward II. Edward III. also bore it for the first thirteen years of his reign, so that this simple but beautiful flag was the royal banner for over one hundred and fifty years. Edward III., on his claim in the year 1340 to be King of France as well as of England, quartered the golden fleurs-de-lys of that kingdom with the lions of England.[21] This remained the Royal Standard throughout the rest of his long reign. Throughout the reign of Richard II. (1377 to 1399) the royal banner was divided in half by an upright line, all on the outer half being like that of Edward III., while the half next the staff was the golden cross and martlets on the blue ground, assigned to Edward the Confessor, his patron saint, as shown in Fig. 19. On the accession of Henry IV. to the throne, the cross and martlets disappeared, and he reverted to the simple quartering of France and England. Originally the fleurs-de-lys were scattered freely over the field, _semée_ or sown, as it is termed heraldically, so that besides several in the centre that showed their complete form, others at the margin were more or less imperfect. On turning to Fig. 188, an early French flag, we see this disposition of them very clearly. Charles V. of France in the year 1365 reduced the number to three, as in Fig. 184, whereupon Henry IV. of England followed suit; his Royal Standard is shown in Fig. 22. This remained the Royal Standard throughout the reigns of Henry V., Henry VI., Edward IV., Edward V., Richard III., Henry VII., Henry VIII., Edward VI., Mary and Elizabeth--a period of two hundred years.
