Text in Danish. Johann Albert Fabricius (1668-1736) was a teacher, scholar and intellectual in the early Age of Enlightenment in Europe. His lifelong passion was Greek and Latin literature on which he spent more than 40 years of categorisation and description. The result was three major works: Bibliotheca Latina, Bibliotheca Græca and Bibliotheca Latina Mediæ et Infirmæ Aetatis, a presentation of nearly 20,000 pages in more than 20 volumes. He wrote and published many other books, mainly within the fields of the humanities and theology. He was a dedicated intellectual who not only aquired academic knowledge, but also devoted himself to investigations into nature and longed for insight into the human nature. In this thesis, Doctor of Philosophy Erik Petersen analyses the work of Fabricius in the light of his German and common European framework as an existential and intellectual process which had emancipation as its principal subject, and academic epoch-making works as its result.
