The oldest known tablet inscribed with the Ten Commandments from the Old Testament sold on Wednesday for $5.04 million, more than double its high estimate.

The stone, which dates back around 1,500 years to the Late Roman-Byzantine era, sparked more than 10 minutes of “intense” bidding, according to a statement from Sotheby’s New York, which hosted the sale. The anonymous buyer plans to donate the artifact to an Israeli institution, it added.

The stone is a remarkable artifact from the ancient world — but it lay forgotten for hundreds of years.

Weighing in at 115 pounds and standing two feet tall, the stone was discovered in 1913 during excavations for a new railway line in the southern part of what is Israel today.
