Manwë decreed a feast more glorious than any that had been held since the coming of the Eldar to Aman... at this time Manwë designed to heal the evil that had arisen among the Noldor, and all were bidden to come to his halls upon Taniquetil, there to put aside the griefs that lay between their princes. ...
Fëanor came indeed, for him alone Manwë had commanded to come; but Finwë came not, nor any others of the Noldor of Formenos.... And Fëanor came not in raiment of festival, and he wore no ornament, neither gold nor silver nor any gem; and he denied the sight of the Silmarils to the Valar and the Eldar... Nevertheless he met Fingolfin before the throne of Manwë and was reconciled, in word.
For Fingolfin held forth his hand, saying 'As I promised, I do now. I release thee and remember no grievance.' Then Fëanor took his hand in silence. [The Silmarillion: Of the Darkening of Valinor]
I wanted to draw this incredibly awkward moment : Fëanor wearing deliberately, insultingly unfancy clothes to a great feast, and Fingolfin all decked out in his best festival clothes, shaking hands, while the Eldar all watch them. Under the cut, a painted version. Colouring faces is something I am yet to get quite right :-/
In case you are interested, I used this rather hilarious reference image fo the poses. I can't imagine what this stock photo is meant to tell us, unless there is a market for stock photos to convey the concept of 'distrust' and 'wariness'. :-D
