You know the grapes of wrath, right? No, not the novel by John Steinbeck; he based the title of his novel on the phrase “grapes of wrath” from the first verse of “The Battle Hymn of the Republic”, also known as “Mine Eyes Have Seen the Glory.” You know the line, right? “Mine eyes have seen the glory of the coming of the Lord: / He is trampling out the vintage where the grapes of wrath are stored.” Well, that refers back to Revelation 14:17–21, in which an angel executes God’s judgment on the earth by harvesting “grapes” for the winepress of the wrath of God. Before the basket press and horizontal screw press became widely used in the late Roman Empire and early Middle Ages, workers would juice grapes by stomping on them–and in the winepress from John’s vision in Revelation, the workers in the winepress squeeze out blood that runs for two hundred miles. And I used to think the chain of references ended there, but no.
