This wonderful book reads like a factual early reader. Part of the Crowell Holiday Book series, this book investigates Christmas, starting with the birth of Jesus and the Nativity story and then going back in time to the festival of Saturnalia and how the similar customs of feasting, decorating the home with ever greens and candles and giving gifts was skilfully changed to celebrate the birth of Christ so that the Pagans wouldn't miss their favourite festival. Modern day customs of Father Christmas, St Nicholas, and St Lucia's day were included. There was some interesting information about how legend has added parts to the Nativity, such as Mary being carried by a donkey, I was surprised to find this mode of transport, however likely for the time, wasn't mentioned in the bible! A very informative read about Christmas with wonderful Barbara Cooney illustrations.
