The Ancient Irish Sagas was the lead article in Theodore DeVinne's famous The Century Magazine, for January 1907 which featured two full-color illustrations by the famous J.C. Leyendecker for the even more famous author, former president Theodore Roosevelt. I couldn't believe it (and didn't know I had the material) until I found it just today!
This is Queen Meave. Roosevelt describes her as: ". . . . the famous warrior-queen, Meave, tall and beautiful, with her white face and yellow hair, terrible in her battle chariot when she drove at full speed into the press of fighting men, and 'fought over the ears of the horses.' Her virtues were those of a warlike barbarian king, and she claimed the like large liberty in morals. Her husband was Ailill, the Connaught king, and, as Meave carefully explained to him in what the old Erse bards called a 'bolster conversation,' their marriage was literally a partnership wherein she demanded from her husband an exact equality of treatment according to her own views and on her own terms; she insisted being that he should be brave, generous, and completely devoid of jealousy!"
