F. Hadland (Frederick Hadland) Davis

Frederick Hadland Davis was an English writer whose work focused on Asian history, religion, folklore, and literature. Public-domain library records and author listings identify him as Frederick Hadland Davis (1882–1956) and preserve several of his books for modern readers.

He is especially associated with Myths & Legends of Japan, a wide-ranging collection of stories and background on Japanese tradition, as well as works such as The Persian Mystics: Jami. Taken together, his books suggest a writer interested in introducing Western audiences to cultures, beliefs, and storytelling traditions beyond Europe in a clear, approachable way.

Reliable biographical detail about his personal life appears to be limited in the sources I could confirm here, so it is safest to remember him chiefly through his surviving books and his role as a popular interpreter of myth, mysticism, and literary tradition.
