The death last month of Leonard Nimoy reminds me of the time when Nimoy’s great character, Mr. Spock, met Abraham Lincoln. It was in 1969, in the third season of Star Trek, and the episode was called “The Savage Curtain.”
A bizarre race of rock-like creatures, the Excalbians, stage “spectacles” with other life forms, to study the effects on them and to glean their philosophies. They reincarnate history’s bad guys and pit them against two creatures who have wandered into their ken, the captain of the starship Enterprise, James T. Kirk, and Spock, the Enterprise’s science officer.
Team Evil is an assemblage of ruthless conquerors: Genghis Khan, Zora of Tiburon, Kahless the Unforgettable (said to be “the Klingon who set the pattern for his planet’s tyrannies”), and Colonel Green, a charismatic master of deceit responsible for the genocide of 37 million people in World War III (and a clear stand-in for Corporal Hitler). They have been promised their hearts’ desire—power—if they win.
