So Notre-Dame made us tremble on April 15, 2019. But why was it “terrible” for Jandun? Jandun could have used venerabilissima, ornatissima, pulcherrima — yet he chooses terribilissima. According to Lewis and Short, terribilis came to mean “demanding reverence, venerable” in late Latin, but it seems Jandun — just a few decades after its construction — might have been trying to capture Notre-Dame’s peculiar “awe-ful” power to impose on us, to shake us, to not leave us alone. To make us tremble. With or without physical fire, it touches us with an internal one.
