The present work investigates the process of developing knowledge during early modern period by using complex networks method. The research is based on semantic, content-related data extracted from a corpus of 359 printed editions, mainly of textbooks used to teach cosmology at European universities between 1472 and 1650. A directed, multi-layer network is constructed in five layers whose structures are defined specifically for the research question at hand. The network is analysed, by making use of the aggregated graph, which accounts for the connectivity between books when any of the potential semantic relations are indistinctly considered. We assess the influence of the different books in the corpus by measuring the normalised node out-degree, as well as disruption factor. Results reveal the emergence of different communities in the aggregated graph that are compared based on different aspects, such as book's format, place of publication, etc. Further analysis demonstrates the time period when knowledge is converged and show its divergence afterwards.
