Book excerpt: Egypt, land of the Bible, has been home since the time of Christ to an ancient sect of Christians called the Copts. According to legend, Mark the Evangelist founded their church in Alexandria in the 1st century AD, when Egypt was under Roman rule and practiced polytheistic religions. Though Egypt long ago became a Muslim nation, the Copts maintained their traditions and rites at monasteries and villages throughout the Nile Valley, the river delta, and the Mediterranean coast, and still do so today.
