Who or what is the origin of the Seven Mountain Mandate?

In Charismatic circles, there is a movement or teaching called the Seven Mountain Mandate. In a nutshell, we are taught that it is God's purpose for the Church or Christians to have influence, or take dominion over **seven specific areas of society/culture**: media, government, education, economy, family, religion, and arts/entertainment. There have been many books on the topic written over the last decade, from authors Lance Walnau, Johnny Enlow, Tommi Femrite, Bronwyn O'Brien, Bill Johnson, Rivkah Isaacs and others. One of the earliest book titles (from 2009) stood out to me: Johnny Enlow's *The Seven Mountain Prophecy*. The title seems to imply that this mandate originates from a specific prophecy uttered by a specific person. **When** did this teaching originate, and **by whom**? I've heard it taught as a general teaching, but I have never learned its origin. Related question: https://christianity.stackexchange.com/questions/42625/whats-the-biblical-basis-for-dominionism
