Difference was one of scale. Much easier when just taking three dozen? pieces of classical latin literature, some of which were different parts of the same opus magnum, then see them cluster to their respective authors and to the other parts of the same piece. More of a "put the pieces into the box" as opposed to a 100,000 pieces puzzle. In the latter case, you just know most of the puzzle pieces will either show the blue sky, or the blue sea, both a similar shade of blue.
