The answer is both. We like to divide our world into two parts in modern western society without realising that it is simply a logical tool we use to make the world easier to understand.
Some examples of this dualistic approach we like to use are:
Right - Wrong
On - Off
Yes - No
...the list goes on. In reality life just isn't that simple or black and white (another one). This relates to your question very easily. The ancient greeks did not differentiate in this way so art WAS technical and science all rolled into one...or to be more specific, not yet divided.
Guess what their word for art was. Techné. The mother of our modern day words technology and technical. So the answer is actually both...
Hope this helps and apologies if I sound pretentious in any way...it's only because I buzz off looking at how we see the world.
