There were practical reasons for reading books aloud. “Domestic lighting was primitive, and prohibitively expensive. Why strain the eyes with insufficient light and small print when a single person with a well-lit book could do the work of many?” Also, eyeglasses were rare until late in the 18th century, so it made sense for a person with good eyesight to read to people whose eyesight was poor. And reading aloud was a way of entertaining others—including people who were illiterate and could not read for themselves—while they were doing housework.
