The White Council

[Bill Ferny]

I disagree that Radagast attended the White Council. He is directly mentioned in Of the Rings of Power and Third Age, but in the same he is absent from the list of those present even though Gandalf and Saruman are mentioned by name:

...and therein were Elrond and Galadriel and Círdan, and other lords of the Eldar, and with them were Mithrandir and Curunír.

It seems that if these Istari were mentioned by name, that the other Istari were not present. It would follow then that Radagast, like the Blue Wizards, was not present.
