So there was an entire culture that lasted longer than Western civilization has existed, and it had run its course before the West was even born. Next week we'll be looking at the Persians and the Greeks. I'll see you then. Crash Course is produced and directed by Stan Muller. The show is written by Raoul Meyer, my high school history teacher, and myself. Our script supervisor is Danica Johnson, and our graphics team is Thought Bubble. Last week's Phrase of the Week was male models.
