Oh come on, no-one has done Pilgrim's Progress yet? Okay, here we go, a quickie only.

A great moral allegory by John Bunyan, written while in Bedford prison for his non-conformist beliefs in about 1667-72, and published in 1678. A second part, written after his release, appeared in 1684.

It is the tale of Christian, who is persuaded by Evangelist to abandon his everyday life and seek the light. He encounters many obstacles, such as the Slough of Despond, Mr Worldly-Wiseman, the Vanity Fair, and the monstrous Apollyon. The second part concerns the travails of his wife Christina on a similar pilgrimage.

It is all delivered in the similitude of a dream.
