Consider the sentence: "The painting was created by Caravaggio". In my opinion this sentence sounds natural and instead of "created" we can use "painted" with exactly the same meaning. What about "generated" and "originated" as synonyms for "created"? Does the sentence sound natural in these cases?
"The painting was generated by Caravaggio"
"The painting was originated by Caravaggio"
We simply would not use those words.
A painting is painted. Created is not even a great word choice.
Maybe... The painting was .... done by Caravaggio.
The painting was.... knocked off by Caravaggio. No, painted is it.
