"Great Catherine" is a play by George Bernard Shaw. The plot focuses on Captain Charles Edstaston, a very prim and proper British military attaché who, in 1776, is assigned to the Imperial Russiancourt in Saint Petersburg, and brings his equally prim fiancée, Claire, with him. In the midst of court intrigue and palace politics, primarily instigated by Catherine's favored statesman and military leader, the drunken, ill-mannered, but crafty Prince Patiomkin, the imperiously commanding, yet concurrently, voraciously intimate Catherine toys with the naive arrival, questioning his rigid beliefs, leading him to drop his guarded mannerisms and, in the process, she also learns certain philosophical truths.
