During Lent we used the Giotto picture study from Simply Charlotte Mason.
The printable kit includes 8 pictures, a read aloud biography, and discussion questions to help you talk through the paintings. There are also suggested resources. We got The Glorious Impossible by Madeleine L’Engle and Giotto Tends the Sheep by Opal Whitney from the library.
We set the pictures out on the piano, visited with them informally, talked about the scenes. It was a gentle, meditative addition to our devotions. Highly recommended.
