Klym Polishchuk (1891–1937), the author of Treasure of the Ages: Ukrainian Legends, was born into a Ukrainian peasant family at the end of the 19th century. He was active in the areas of art and literature.

Kyle Polishchuk’s writing career was disrupted first by arrest and exile to Russia and then mobilisation to fight in World War I. During the 1920s, his literary output included a range of novels and accounts of the Soviet revolution. He was fascinated by folklore and, in 1921, produced his collection of Gothic tales, Treasure of the Ages: Ukrainian Legends.

In 1929, he was again arrested and incarcerated in Soviet labour camps until his execution in Sandarmokh in 1937.
