The Bible in Armenian (Amsterdam, 1666).
This detail comes from the first printed Armenian Bible: "The editio princeps of the Armenian Bible ... In the 17th century Armenian manuscript Bibles had become so scarce and costly that the Patriarch Jacobus Caractri about 1662 despatched an ecclesiastic named Uscan (or Osgan) to Europe to arrange for the printing of an edition of the Armenian Scriptures. This Uscan ... went first to Rome, but afterwards moved to Amsterdam, where he supervised the publication of this Bible" (Darlow & Moule).
This copy has a plain calf binding (probably not the original), but has intricate gauffering on the edges of the textblock.
