Yes, that's confusing writing! I'll give it a shot. To greatly simplify:
"Men who are great artists may invite other artists to use the same kind of techniques in their own works. Those other artists who learn to use the techniques of these great men are geniuses, and can learn from the artists who lived before them."
So no, recommend doesn't = consider, it's more like, "although they (men who are great artists) should not be imitated exactly, aspects of their talents might be incorporated in your own work."
"This use" (of [artists of] the Flemish, Venetian, and French schools) is the "transfer of excellences" into the artist's work of the "interesting expression" and "force and energy" of the artist who has gone before.
What in the world are you reading? It sounds like a scholarly treatise written a hundred years ago!
