Why Irish Mythology Names Are So Powerful
Irish mythology, particularly as preserved in the Mythological Cycle, Ulster Cycle, Fenian Cycle, and Historical Cycle, is filled with larger-than-life characters. These names have stood the test of time—not just because they sound beautiful, but because they’re tied to timeless themes: courage, transformation, tragedy, love, and fate.
Using or learning these names helps you connect with Irish culture in a deeply authentic way. Plus, many of them are still used in modern Ireland (and beyond), keeping the ancient stories alive in everyday life.
