Something wrong with the chronology.
The term "Dark Ages", which as Shiranui points out is now out of favour as it implies a false picture of civilisation at that time, was generally applied to the period immediately after the fall of the Western Roman empire, say up to 900AD. Citing events from 1600 is at least 500 years out.
But in any case, This is what Wiki has to say about the idea:
" As the accomplishments of the era came to be better understood in the 18th and 20th centuries, scholars began restricting the "Dark Ages" appellation to the
Early Middle Ages (c. 5th–10th century),
[6][7][8] and now scholars also reject its usage in this period.
[9] The majority of modern scholars avoid the term altogether due to its negative connotations, finding it misleading and inaccurate.
[10][11][12] The pejorative meaning remains in use,
[1][2][13] typically in popular culture which often mischaracterises the Middle Ages as a time of unchecked violence and backwardness.

I've attended Easter Mass at Charlemagne's octagonal chapel in Aachen, built in 800AD. It left me in no doubt this was a time of serious artistic and architectural accomplishment in Northern Europe.
