Since one of the qualities most people praise in my books is their historical accuracy, I want to point out a couple of mistakes that, in spite of my best efforts, made it into this series. They will be corrected in our next edition, but in the meantime, you should be aware of them as you teach your children.

1. Calvin, first edition, page 6. The map in the first edition was not totally accurate because the line marking the Papal States was drawn too high. This has been corrected in the newer version.
2. Augustine, page 7. When Augustine was born, Milan – not Rome – was the capital of the Western Roman Empire.
3. Athanasius, pages 4 and 29. Nicea has been marked too far from Constantinople.
