Here are some one liners...
A Suddenly Missing Island -- The 2nd largest volcanic eruption in history makes two small islands out of one large island and a really big empty space in between.
The New Hussite King -- Bohemia needs a new king since the previous one died mysteriously. They choose a Hussite. FYI, modern experts say the young king died of leukemia.
The Erfurt Treasure -- The Jews are expelled from Erfurt, Germany once again. Apparently, the Jews had buried gold and solver coins that were uncovered in the 1990s. They call it the Erfurt Treasure and it is on display in the synagogue/museum.
