This watercolour, dated 1927, was published in The Silmarillion Calendar 1978, together with the heraldic devices of Fe:anor, Fingolfin, Hador, and Ea:rendil, who were associated with the region (Ea:rendil through his father Tuor). In this book these devices have been grouped with others that appeared in the same Calendar (see no. 47). Lake Mithrim lay in the east of Hithlum; about its shores the divided hosts of the Noldorin Elves made their encampments after their return to Middle-earth (The Silmarillion Chapter 13, Of the Return of the Noldor).
