Direct responses to this story include the stories "The Deadly Mission of Phineas Snodgrass" (1962) by Frederik Pohl, and "The Man Who Came Early" (1956) by Poul Anderson. In the Pohl tale, a man travels back to 1 BC and teaches modern medicine, causing a population explosion. It ends with the fantastically overpopulated alternate timeline sending someone back to assassinate the title character, allowing darkness to fall for thankful billions. It was reprinted in Harry Turtledove's 2005 tribute anthology honoring L. Sprague de Camp, "" and the 2011 anthology "Lest Darkness Fall and Related Stories". The Anderson piece is a tale of an American airman sent by a storm (like Padway) to Saga Age Iceland; the story deals with the effect of his innovations.
