Filip Fabricius was born in Mikulov, Moravia (Zikmund Winter incorrectly suggested Mohelnice).
[1] He studied at Prague Jesuit Academy (first mentioned there in 1586 as a rhetoric student) and became a Bachelor in 1588 and Master a year later.
[1] On 23 May 1618 Filip Fabricius was present in the offices of the Bohemian Court Chancery on Prague Castle together with Catholic Lords Regent Jaroslav Bořita of Martinice, Vilém Slavata of Chlum and Košumberk, Adam of Šternberk and Děpolt of Lobkowicz when armed Protestant Lords arrived and required confessions of guilt for the anti-Protestant policies of the king.
Fabricius was one of the first people who informed the Vienna royal court of the Protestant rebellion in Prague.
After the Battle of White Mountain he was appointed a chamber councillor, vice-chamberlain of the dowry cities, sheriff of Mladá Boleslav region, and a member of some other important councils.
