Lex Loizides has been doing a great series of blogs on church history, but little did I know that he's actually a first-hand source! For example, he's just done a post on Wycliffe, who was a fantastic preacher as can be seen in this great painting:
John Wycliffe. In the villages and towns the people listened eagerly to Wycliffe and his preachers reading passages from the Bible - in English. One in particular, in the lower right hand corner, seems in earnest prayer... perhaps due to the proximity of the axe to his face.
