Luther's Commentary on Genesis contains a passage which concludes that "the soul does not sleep (anima non sic dormit), but wakes (sed vigilat) and experiences visions". Francis Blackburne in 1765 argued that John Jortin misread this and other passages from Luther, while Gottfried Fritschel pointed out in 1867 that it actually refers to the soul of a man "in this life" (homo enim in hac vita) tired from his daily labour (defatigus diurno labore) who at night enters his bedchamber (sub noctem intrat in cubiculum suum) and whose sleep is interrupted by dreams.
Where did Luther say that the soul doesn't sleep, but rather has visions? Who stated that John Jortin misunderstood Luther? When did Blackburne make his argument about Luther and souls? Who pointed out that the passage under dispute actually refers to a living man? What did Fritschel say the man's sleep was disturbed by?
