Christian Gueintz (13 October 1592 – 3 April 1650) was a teacher and writer-grammarian. He was qualified and taught in several mainstream subjects of the time, notably philosophy, theology, and law. He lived during the first half of the seventeenth century, a period characterised by Baroque architecture and, in northern Germany, repeatedly disrupted by destructive war, which at various points had a dislocating impact on his career, and through which he demonstrated impressive qualities of persistence.
