This is a publication of a diptych in which names of the dead and living Orthodox faithful with members of their families (including tsars, princes, patriarchs of Muscovy, and Ukrainian hetmans) were entered by emissaries of St. Catherine's Monastery to Muscovy, the Ukrainian Hetmanate, the Polish-Lithuanian Commonwealth, the Crimea, and the Ottoman Empire from the 1630s to the 1730s in exchange for alms for the monastery and the prayers of its monks. Entries in the diptych are mostly in Ukrainian, even from places in the Crimea and Istanbul with its environs; hence the Ukrainian name pomjanyk is used to describe it.
This diptych had been known to scholars since at least the 1940s, but it was only the visit to Mt. Sinai by Professor Moshe Altbauer from Hebrew University in Jerusalem that led to the photographing and publishing of this valuable document.
The volume contains a preface, photoreproduction of the original, and an index of personal and geographic names.
