In 1831 Victor Hugo wrote that he was hearing “the dull sound of revolution, still deep down in the earth, pushing out under every kingdom in Europe its subterranean galleries from the central shaft of the mine which is Paris.” In 1847 the sound grew louder. In 1848 the revolution erupted, beginning in Sicily and spreading to France, Germany, Italy, and the Austrian Empire. Europe was on fire. In 2021, a dull sound of revolution can be heard. For whom the bell tolls, this time—we will soon find out.
