"The price of Griboyedov's blood" was what Russian diplomats called Alisher Navoi's Early Diwan. This is the oldest surviving lifetime manuscripts by the great Uzbek poet. It was copied in 1465-1466, and much later, along with the Shah diamond, was transferred by the Iranian ruler to the Russian Emperor Nicholas I as an apology for the murder of the Russian ambassador Alexander Griboyedov in Tehran. The Early Diwan was compiled when Navoi was about 25 years old. Currently, two more lifetime manuscripts by Alisher Navoi are stored in the Russian National Library. These are Hamsa copied in 1493 and Kulliyat rewritten in the late 15th–early 16th century. In total, the book-album The Works of Alisher Navoi in Fine Books of the 15th–16th Centuries (from the Collection of the Russian National Library, St. Petersburg, Russia) includes more than 100 works representing the richness of the manuscript heritage of Uzbekistan.
