The other main Russian coat of arms, the image of St George slaying the dragon, is contemporaneous. In its first form, as a rider armed with a spear, it is found in the seal of Vasili I of Moscow in 1390. At the time of Ivan III, the dragon was added, but the final association with Saint George was not made until 1730, when it was described as such in an Imperial decree. Eventually, St George became the patron saint of Moscow (and, by extension, of Russia).
