I am glad that this question has piqued your interest and that you were able to provide such a fascinating comment about it. To be honest I haven't come across anyone who might be able to enlighten me on this question from a historical perspective as I am trying to trace where the origin of this bifurcation might have occurred.
To me it seems like there are cultures where art & science are seen as one of the same (or at least by individuals - Leonardo Da Vinci is usually the first that comes to mind). I think many aspects of human culture show that these two concepts intertwine, in particular religion (and mythology) touches many areas of science and art, as does philosophy. Mathematics has been described as a way to describe the beauty of nature in a systematic way, and architecture bridges the gap between engineering and the natural environment (when done properly).
Maybe not many other people care about this question, but this is the beauty of Steemit! Where I could not find people in my social circles that were interested enough to ponder it further, someone who I literally just crossed path on Steemit has shed a new light on my 'investigation'. If you write an article about it I would love to see it on the Steem Magazine (@steemfreepress is an initiative started by @tonyr that I am very excited about).
Well, of course, the difference between "mythology" and "science" is very much a cultural one. There are plenty of people out there who believe that the Biblical creation story is fact and that the earth is only 6,000 years old. The entire principle of studying the Humanities at its core is to study the intersection of arts and sciences as one discipline.
I think you would really like @monicacope. She's an artist and doctor.
I think in high school they grouped the subjects into two different categories: Science and Arts & Humanities. But for some reason they also had Social Sciences. Just had a quick peek at @monicacope and it looks really interesting as well. There are so many artists here on Steemit plus a very active @steemstem group too (they just had a meetup at CERN!). Have a look at the Steemtopia Network of Learning for some names I have put together (and am trying to add to): https://steemit.com/makesteemitgreat-again/@fibrefox/the-steemtopia-network-of-learning-update-bigger-plans-ahead
