§ Of Túrin Turambar The Silmarillion

'Another gift I will give to you, Cúthalion,' said Melian, 'that shall be your help in the wild, and the help also of those whom you choose.' And she gave him store of lembas, the waybread of the Elves, wrapped in leaves of silver, and the threads that bound it were sealed at the knots with the seal of the Queen, a wafer of white wax shaped as a single flower of Telperion; for according to the customs of the Eldalië the keeping and giving of lembas belonged to the Queen alone. In nothing did Melian show greater favour to Túrin than in this gift; for the Eldar had never before allowed Men to use this waybread, and seldom did so again.
