The first painting to be exhibited after the public revelation of the meaning of "PRB" was William Holman Hunt's "A Converted British Family Sheltering a Christian Priest from the Persecution of the Druids." The title of the painting is rather self-explanatory, and like many of the early Pre-Raphaelite works, it dealt with religious themes through a rather syncretistic lens.
You might also recognize the face of the girl on the right of the priest: it's Lizzie Siddal, although Holman Hunt has portrayed her rather differently than Rossetti generally does. This painting caused an uproar when it was first displayed because of the "nudity" of some of the figures. This might have merely been a reaction to the fact that the public was now aware of the existence of the Pre-Raphaelites and did not approve of the Brotherhood.
This painting is filled with overt Christian symbolism. You can see that thorns are being removed from the priest's clothing and the women are preparing to bathe his feet--an allusion to Christ on the cross. Immediately above the priest is a red cross that indicates that the family sheltering the priest are Christian converts. A lamp burns just below, highlighting the fact that, in time, things will change for Christians in England. Grapes are being grown on the arbour above, hinting at the wine used at mass (one of the young boys on the left hand of the canvas is drinking from a chalice). At the right of the canvas, a net rests on one of the beams supporting the roof. Interestingly, while nets are symbols of Christianity (Christ made his disciples "fishers of men"), they also are a reference to the fact that this family has abandoned some key Druidic practices. The Druids believed fish were sacred and did not allow fishing.
