Thursday, 13 October 2941 T.A.: In the shadow of Erebor

A rather Tolkienish impression of Menelvagor over Erebor

It was probably on this day, in 2941 T. A., that Bilbo already suggested to relocate the base camp from the slope of Ravenhill to the western side of the Lonely Mountain. The published "Hobbit" does not imply specific dates but Tolkien's jotted notes as published by Rateliff suggest that the events between establishing the camp at Ravenhill and opening the Hidden Door were more compressed than the text suggests: nine days altogether, which complies with the timeline derived from the lunar phases.

The last moon of autumn was approaching its last quarter.
