Rather than re-reading the Purgatorio this Easter, as I so often do, I re-read The Pilgrim’s Progress by John Bunyan (available electronically at CCEL). This classic book is also an allegory of the Christian pilgrimage:
The Wicket Gate and the three Shining Ones
“Then they read to him some of the worthy acts that some of his servants had done; as how they had subdued kingdoms, wrought righteousness, obtained promises, stopped the mouths of lions...” and Christian battles Apollyon
It was good to revisit this classic, although the allegory does seem to limp in one or two places. All the images above are labelled as public domain.
