Hunger Stone : The recent droughts in Europe once again made visible the “Hunger Stones” in some Czech and German rivers. These stones were used to mark desperately low river levels that would forecast famines.
One such stone is on the banks of the Elbe River, which begins in the Czech Republic and flows through Germany. The boulder dates back to 1616 and is etched with a warning in German: “Wenn du mich seehst, dann weine” — “If you see me, then weep,” according to a Google translation of the phrase.
“Before 1900, the following droughts are commemorated on the stone: 1417, 1616, 1707, 1746, 1790, 1800, 1811, 1830, 1842, 1868, 1892, and 1893.”
