In an atheist society, such as the communist one, all forms of the sacred were anathematized and fiercly sanctioned. Nevertheless, despite these ideological barriers, important articles and volumes of Byzantine — and sometimes Gregorian — musicological research were published in totalitarian Romania. Numerous Romanian scholars participated at international congresses and symposia, thus benefiting of scholarships and research stages not only in the socialist states, but also in places regarded as ‘affected by viruses,’ such as the USA or the libraries on Mount Athos (Greece). This article discusses the mechanisms through which the research on religious music in Romania managed to avoid ideological censorship, the forms of camouflage and dissimulation of musicological information with religious subject that managed to integrate and even impose over the aesthetic visions of the Party. The article also refers to cultural politics enthusiastically supporting research and valuing the heritage of ancient music as a fundamental source for composers and their creations dedicated to the masses.
