Seven Periods of the Apocalypse, According to Moses Lowman
From Jonathan Edwards Works: Apocalyptic Writings (WJE Online Vol. 5), pg 55-59

Jonathan Edwards (October 5, 1703 – March 22, 1758) based his interpretation of Revelation on Moses Lowman's (1680–1752) timeline of Revelation. Below is a chart that I obtain from the Edwards Center at Yale, that outlines the events of Revelation, and then lists the corresponding epocs in history that Lowman believed the symbols foretold, as well as their beliefs based on what would happen after their time. Edward's interpretation was not the same as Lowman's, but you can read more about it in Edward's Apocalyptic Writings, pgs 55-59 at the Edwards Center. I believe Edwards agreed that he was living during the fifth vail/bowl.
