Kristián was one of those students of the Brethren whom Comenius looked after in his role as a senior of the Brethren, and whose theological studies in Geneva he followed. In 1663 Comenius came to Nigrin’s aid in resolving some financial difficulties, sending him money for a journey to Leipzig and Poland which, for reasons of health, he recommended be made on foot – in his letter he recalls his journey from Heidelberg. Nigrin served as the Czech secretary to the English (Welsh) Earl of Pembroke and Montgomery, mediating written contact with Mikuláš Drabík. Comenius entrusted his son Daniel and Kristián Nigrin with the publication of his Consultatio. From 1675 Nigrin worked with Pavel Hartmann at Oxford on the publication of writings from Comenius’ effects, but the prepared texts were not printed.
