They concluded that such an eclipse would have been visible, for thirty minutes, from Jerusalem and suggested the gospel reference to a solar eclipse was the result of a scribe wrongly amending a text. Historian David Henige dismisses this explanation as 'indefensible' and astronomer Bradley Schaefer points out that the lunar eclipse would not have been visible during daylight hours.

Problem: In 2003, the remains of a mosaic pavement were discovered under the ruins of the Bizere Monastery near the River Mureş in present-day Romania. The panels depict real or fantastic animal, floral, solar and geometric representations. Some archeologists supposed that it was the floor of an Orthodox church, built some time between the 10th and 11th century. Other experts claim that it was part of the later Catholic monastery on the site because it shows the signs of strong Italianate influence. The monastery was situated that time in the territory of the Kingdom of Hungary.

The answer is the following: between the 10th and 11th century
