English author G.K. Chesterton thought that “over the hills and far away” was the most poetic line in all of literature. The tune “Over the Hills and Far Away” mentioned in the nursery rhyme is a traditional British song from the late 17th or early 18th century. It was a siren’s song that promised wonder and adventure beyond the blue horizon. Gwyn Thomas, a fine though neglected Welsh writer, heard the song during his early-20th-century childhood in the Rhondda Valley, the heart of the south Wales coal region. Honeycombed by mines, the Rhondda’s spirit lay at the core of Thomas’ heart and imagination, and he distilled a mordant humor from the dark vibes of the life that he knew there.
