Note 1 — EAGLE TOWER, CAERNARVON CASTLE.
Reading edition
The origin of the motto Ich Dien—I serve—is generally attributed to Edward the Black Prince who, in leading the vanguard of his army to the battle of Cressy, slew John of Luxemburg, King of Bohemia, and then deplumed his helmet of those ostrich feathers which, in memory of this victory, became his cognisance,—sometimes using one feather, at others three, as appears on his seals and tomb, with scrolls containing this motto, Ich Dien. But the ancient arms of the princes of Wales, while they were independent sovereigns, were quarterly gules and or, four lions passant, counterchanged. The Charter of Edward the First to his son is dated March 24th, 1305,—i.e. when the Prince had attained his majority.
