one of the most distinguished Flemish poets of his generation.

Of a retiring nature, van Nijlen, a high official with the Ministry of Justice in Brussels, usually published his verse in limited editions. Among his early volumes were Het angezicht der aarde (1923; “The Face of the Earth”), De vogel phoenix (1928; “The Phoenix Bird”), and Geheimschrift (1934; “Secret Writing”). He gained a wider audience when in 1938 he at last published a one-volume selection from his poems, Gedichten, 1904–1938. Subsequent publications included De Dauuwtrapper (1947; “The Dew Trapper”) and Te laat voor deze wereld (1957; “Too Late for This World”).

Van Nijlen's characteristic tone is melancholic and elegiac, reflecting his disillusionment with the modern world. His verses recall the Romantics' longing to escape to a simpler and truer life; they are marked, however, by a classical clarity and finish. Van Nijlen also wrote studies of the French authors Charles Peguy (1919) and Francis Jammes (Jammes, Francis) (1918).
