In a church on the Princes’ Islands of Istanbul, a masterpiece and Byzantine treasure awaited discovery. This unique bilateral post-Byzantine icon of Panagia Eleousa held a peculiar feature: on its reverse side, there was another painted icon from the same time period, which had remained “hidden” for over a century inside a heavy metal box, kept in the Church of Panagia Eleousa on Büyükada/Pringipos. This magnificent, rare, and unique artifact, often regarded as the Byzantine Mona Lisa, has endured through the centuries, conveying numerous historical, social, and artistic messages. With the expertise of a conservator, who tends to it as an art doctor, it has been safeguarded for future generations. Currently, this masterpiece is housed at the Church of Panagia Eleousa in Büyükada/Pringipos, Istanbul.
