In the year of the Poltava victory of Russia (1709), King Frederick IV of Denmark sent the naval commander of the Danish Service, Just Juhl, to Peter I as his envoy. A brave sailor, an intelligent diplomat, Vice Admiral Just Juhl left remarkable diary entries of his stay in Russia. These are careful notes from a contemporary, a participant in the events. Observation, interest in the details of the life of the Russian people, attention to the details of everyday life, especially to secular and church rituals, technical, economic, distinguishes the Dane’s notes. As well as their emotionality, which enlivens the story, in some episodes Yul shows both the strength and weakness of the Russian emperor, is horrified by the drunken barbarity of the then royal court, but also admires the intelligence, resourcefulness and... cunning of Peter. The same applies to assessments of other historical figures, both Russian and foreign. These notes are not easy reading, but very fascinating. The manuscript was restored and translated by the remarkable diplomat and historian Yuri Shcherbachev back in 1899, but is of great interest to history buffs today.
