Caspar Barlaeus

Caspar Barlaeus (February 12, 1584 – January 14, 1648) was a Dutch polymath and Renaissance humanist, a theologian, poet, and historian. Life Born Caspar (Kaspar) van Baerle in Antwerp, Barlaeus' parents fled the city when it was occupied by Spanish troops shortly after his birth. They settled in Zaltbommel, where his father eventually would become head of the Latin school. Caspar studied theology and philosophy at the University of Leiden. After his study, he preached for 1.5 years in the village of Nieuwe-Tonge, before returning to Leiden in 1612 as an under-regent of a college. From 1617 he also was professor in philosophy at the university. Because of his remonstrant sympathies, he was forced out of this job in 1619. He then studied and graduated in medicines (in Caen), but never practiced professionally. From 1631, he was professor of philosophy and rhetoric at the Amsterdam Athenaeum, Athenaeum Illustre), which is commonly regarded as the predecessor of the University of Amsterdam; the Athenaeum had its seat in the fourteenth-century Agnietenkapel. In January 1632, Barlaeus, along with Gerard Vossius, held his inaugural speech at the Amsterdam Atheneum. Barlaeus later encouraged Martinus Hortensius to lecture –and give an inaugural speech- at the same Institution. One of his huge patrons was Amsterdam burgomaster Andries de Graeff. Barlaeus suffered from mental illness including the delusion that he was made of glass (the Glass delusion) though Gill Speak refers to his glass delusion as ‘unsubstantiated’.
