The commentaries are limited in their scope, being mostly concerned to discuss the implications of what is said within the context of the Tales themselves, and to compare them with the published Silmarillion.I have eschewed parallels,sources, influences;and have mostly avoided the complexities of the development between the Lost Tales and the published work (since to indicate these even cursorily would, I think, be distracting),treating the matter in a simplified way, as between two fixed points.
