A few ideas for expanding your blog post research. These sources are also meant to help you think outside the box and explore topics, people, and ideas you may not be familiar with yet. They aren't exactly introductory, but most are pretty approachable and you won't have to worry too much about credibility issues.
I'm always on the look out for additional websites, podcasts, and databases to include. If you come across something in your own research, do add it to the comments!

Much of the content is more recent than 1500, but a fair bit of medieval and early modern art and music is available.
