Pyotr Ivanovich Kafarov (Pre-reform Russian: Петръ Ива́новичъ Кафа́ровъ) (Modern Russian: Пётр Ива́нович Кафа́ров), also known by his monastic name Palladius (Pre-reform Russian: Палла́дій) (Modern Russian: Палла́дий), (1817, Chistopol – 1878), was an early Russian sinologist.
Kafarov was born in the family of an Orthodox priest. He studied in Kazan seminary and Saint-Petersbourg Academy, from which was sent to the Russian Orthodox Mission in China.
Like his teacher Hyacinth (Bichurin), Palladius was a Russian Orthodox monk. During his stay in China, he discovered and published many invaluable manuscripts, including The Secret History of the Mongols.
For more than three decades, Archimandrite Palladius headed the Russian Orthodox mission in China and held ethnographic and linguistic research there.
Kafarov designed a Cyrillization system for the Chinese language, known as the Palladius system. This system has remained the basis for official transcription of Chinese personal and geographical names in Russia ever since.
The Chinese-Russian Dictionary composed by Archimandrite Palladius remains a well-known work even today.
