oh god Thanks to the educational kat_kat, I learned today about the existence of a unique cannon from the beginning of the 17th century, during the reign of Mikhail Romanov, on which the Latin inscription was stamped: The great lord Tsar and the great leader Michael Podroits of all bears.
Translation: To the Grand Tsar and Grand Duke Mikhail Fedorovich, sovereign of all bears.
Of all the Russians, of course, there had to be "all of Rus". But the perfect typo made everything much, much better.
