What details does Bede provide his readers to give
them a sense of what Britain is like?

It provides geographical details, as well as telling elements of the history of England and the expansion of Christianity.

Explanation:

"The Ecclesiastical History of the English People" was written Venerable Bede with the focus on explaining the moments of conflict between the pre-Schism Roman Rite and Celtic Christianity and how it moved and impacted England and the entire British empire.

In order to situate readers on the situation in England at that time, the author provides several geographical details as well as historical points that show what England was like from a spatial and even cultural point of view.
