On March 3, 1861, 7 men comprising of a few doctors, a lawyer, a publisher, and the Consul General of Greece met to discuss the creation of a society aimed at enhancing Hellenic culture among first the residents of Constantinople but also across the entire Ottoman Empire. Then on April 17th of the same year, the Greek Literary Society in Constantinople ( Ὁ ἐν Κωνσταντινουπόλει Ἑλληνικὸς Φιλολογικὸς Σύλλογος) colloquially referred to as the Syllogos, had its inaugural meeting. Operating out of headquarters in Beyoğlu, the Syllogos ran from 1861 to 1922, primarily as a scholarly society for literary and scientific, especially medical, studies - publishing an annual journal called the Syngramma Periodikon, holding public lectures, and creating a wide ranging network of scholars within the Empire and beyond into Europe.

This digital mapping project serves as a virtual repository of layered information about the Syllogos’s legacy: the extent of its scholarship through its connections with various institutions and individuals, the libraries that preserve its journals, and more. This open-source map not only supports research on the Syllogos but also strives to perpetuate the institution’s intellectual impact, helping to sustain its global reach and connectivity in a modern context.
