It’s a heavy book. Quite literally I mean. Weighing more than 57 pounds (27 kgs), it’s one of the largest surviving texts from the 14th century.

Nuremberg Mahzor will be on display at the Israel Museum for the first time ever starting September 18.

The manuscript, a prayer book, was written in Germany in 1331 and of its original 528  leaves, only 7 are missing. It contains 22 illuminations inlaid with gold and silver and approximately 100 prayers and liturgical poems that have never been published. Within the margins, rabbinical commentary has also been printed.

The exhibit is set to open just two days before Rosh Hashana, the Jewish New Year holiday.
