From Dolmen Tree Art, the website of James Dunning:

"The artist is James Dunning, who has served as jack of many trades, to include linguist, soldier-clerk, free-lance translator / interpreter, teacher, professional student, chemist and pharmaceutical researcher, archivist, author and editor of scientific reports (et al.), and musician in Irish and international music. He has acquired no formal art training other than the casual observation and homage of the eye to nature and to works and techniques admired, but is now offering a portfolio, including drawings in pen and ink and other media."

His artwork appears in A Tolkienian Mathomium by Mark T. Hooker
