This clock is made on the occasion of the division of the lands of Schwarzburg. In 1571, the four sons of Count Günther XL ( also known as “Günther with the heavy jaw” and Günther the Rich) of Schwarzburg-Blankenberg(1499-1552), divided amongst themselves, after many years of bitter quarreling over their inheritance, the lands their father had united. One of the four sons, Count Wilhelm I (1534-1590), commissioned this clock to commemorate the event. Wilhelm had gained the family lands in Frankenhausen, including the castle, which is today a museum,. The clock bears the Schwarzburger coat of arms and the coat of arms of Wilhelm’s wife Elisabeth von Schlick in Passaun ( 1522-1590), the Schwarzburgs were one of the most oldest noble families of Thuringia until the death of the last family member in 1971.
Genesis ( 28:11-19)
Jacob laid down to sleep on the ground while he was travelling and dreamed of a vision in which a ladder stretched from the Erath to Heaven, with angels ascending and descending the ladder, with God above. In the dream God spoke to Jacob and said: “The land in which you lie I will give to you and to your descendents.”
