This might be the most accessible way to read the 17th century diary of Samuel Pepys' – as a blog with one post for each diary entry.

Still quite a difficult read to be honest, with sentences like these:

This day Mr. Pierce, the surgeon, was with me; and tells me how this business of my Lord Chancellor’s was certainly designed in my Lady Castlemayne’s chamber; and that, when he went from the King on Monday morning, she was in bed, though about twelve o’clock, and ran out in her smock into her aviary looking into White Hall garden; and thither her woman brought her her nightgown; and stood joying herself at the old man’s going away: and several of the gallants of White Hall, of which there were many staying to see the Chancellor return, did talk to her in her birdcage; among others, Blancford, telling her she was the bird of paradise.
