Visual documents give us important clues in recognizing about our musical heritage. It can be said that the oldest of the visual documents about Mevleviyeh in the Ottoman Empire was miniature art. Later on, the art of painting became influential (17-18th century) and the figures of music were included in the art of painting. The widespread use of photographs and postcards, a means of visual communication in the 19th century Ottoman Empire, includes both cultural and sociological reflections of this state, which is our historical and cultural heritage today. Research on the printing, spreading of the postcards and the periods in which the pictures or photographs belong to them is extremely limited. Therefore, this research is important. The way in which the religious music represented in the Ottoman Empire through postcards was the starting point of the research. In this research, twenty-four documents were obtained from the Atatürk Library belonging to the Ottoman Religious Music. Each documents were classified as photographs, postcards and anonymous works and they were examined separately. The fact that some documents have information about the typographer, publisher and photographer has made it easier for the determination of the period. According to the data, these documents belong to the 19th century and the first half of the 20th century.
