From the experts:
Though short and brisk, no nickname name could have a more creative image. Comic actor Chris O'Dowd named his son Art, as in his native Ireland it's used as a name on its own, separate from Arthur., coming from an ancient word for “”a bear,”” and used in the sense of “”outstanding warrior”” or “”champion.”” A pagan High King of Ireland, Art’s rule was so honest that two angels hovered over him in battle.
