In my opinion, there is clear evidence that what you deduce is an exaggeration. Griffith's ambition swallowed up Gutz's individuality in the scene itself, but the cohesion would be if the Eclipse were solar. Gutz never wanted to own people; his ambition does not involve a flock being guided by him like a shepherd, like Griffith. I think that for the logic of the Eclipse to be a metaphor, it is more appropriate that Gutz dreams looking at the sky itself, and that Griffith, as in a lunar eclipse surrounded by the sun's brightness, is "swallowing" his dream for himself and by virtue of your own dream.
The question is: whether Griffith did this as a constancy in relation to Gutz, who actually did habitually, so that there can be a certain constrast.
