BERTKEN, Suster

Suster Bertken (Sister Bertie), born Berta Jacobsdochter, was a late-medieval Dutch anchorite (recluse), poet, and writer based in Utrecht, Netherlands. Her lyrics have been adapted into modern musical compositions, and she was the first Dutch woman to have her work published in print. Bertken was born an illegitimate child into the prominent Lichtenberg family. Her father, Jacob van Lichtenberg, was a high-ranking cleric and provost of the Collegiate Church of St. Peter in Utrecht. Despite her status as a "bastard child," she received an exceptional education for a girl in the 15th century, allowing her to become highly literate. Around 1456 or 1457, at roughly 30 years old, Bertken chose a life of total religious devotion. She financed the construction of a small, unheated brick cell built against the wall of the Buurkerk (the civic church in the bustling center of Utrecht) and was formally walled inside. Bertken wrote in the vernacular (Middle Dutch) rather than Latin, making her prose accessible. Her writings focused heavily on Christ's passion and the intense, mystical relationship between the soul and God. Two booklets survived and were printed shortly after her death in 1516: "Het boecxken van dye passie" (The Booklet of the Passion) – a prose text containing meditations on Christ's suffering and "Suster Bertkens boeck" – a collection of prayers, a Christmas tract, a dialogue, and eight religious songs/poems.

Bertken passed away on June 25, 1514, at around 87 years old. Her death was met with deep public mourning; the Utrecht cathedral bells were tolled twice (a rare honor reserved for high clergy), and she was buried inside her cell as she requested. Today, a memorial stone marks the spot where her cell once stood on Utrecht’s Choorstraat.
