"Renaissance artists were the technicians of course. That’s what they were known for."
That's only partially true.
While Renaissance masters usually had the skill to execute a fully finished work, and probably did so during their own apprenticeship, by the time they became masters they often had workshops of dozens or even hundreds of assistants who did almost all of the work for them. After the work was almost complete, the master might come in and put on some finishing touches.
There's lots of art out there these days that's misattributed to the master when it was actually done by one of his assistants in the workshop, whose training was usually centered around creating art that looked just like the master's.
