Peter also demanded changes in mannerisms and language among nobles. To supply Russians with a basic set of “proper” morals and habits, he ordered publication of manuals on Western etiquette. The most popular of these was "The Honourable Mirror of Youth or A Guide to Social Conduct Gathered from Various Authors", a compilation of rules of conduct from numerous European sources, initially published in St. Petersburg in 1717. He also encouraged the learning of foreign languages especially French, which was the foremost political and intellectual language of Europe at the time. For the nobility, these changes felt even more forced than fashion regulations. As with clothing, there was uniform acceptance of Western mannerisms at court but general disregard for them outside of St. Petersburg. Furthermore, when Westerners visited Peter's court they found the image and personality of the courtiers to appear forced and awkward. Friedrich Christian Weber, a representative of Britain, commented in 1716 that the nobles “wear the German Dress; but it is easy to observe on many, that they have not been long used to it”.
