The Cromlech on Howth's illustrator, Margaret Stokes later edited Dunraven's Notes on Irish Architecture. She wrote and illustrated Early Christian Art In Ireland (1887). She produced two works on early medieval Irish saints in Europe, Six Months in the Apennines (1892) and Three Months in The Forest of France (1895). Her final work, The High Crosses of Ireland, was unfinished at her death. Stokes was credited on the title page of The Cromlech on Howth only by an elaborate monogram of her initials.
