Psychological depth in Tolkien's characters

[Eurytus]

hmmm... very interesting. Apart from the fact that it is UT's The History of Galadriel and Celeborn [and behind that HoM-E XII's Shibboleth of Feanor] that reveal her as Feanor's equal you seem to be at odds with yourself on the 'multi-source reading shows the full character' issue.

Please check the title of the thread, the title of the thread is about psychological depth. Finding out about Galadriel’s ranking from other works has nothing to do with her psyche. Hence there is no contradiction at all.
