According to the memoirs of B. I. Kurakina “a man of great mind, and especially sharpness, but not diligent about affairs, he still loved fun, and was especially prone to drinking. And this is the first who began to get along with officers and foreign merchants. And because of his inclination towards foreigners, he brought them into frankness to the court and the royal majesty inclined them into mercy."
