Here is a folktale from the north of the Peak District.
Beside Dovestones Reservoir in the Upper Tame Valley, not far from Mossley, stand two hills: Alphin Pike and Alderman’s Hill. These were once the homes of two giants, Alphin and Alder, who were friends until they both fell in love with Rimmon, a water nymph, who lived in the sparkling water of Chew Brook in the valley below. Rimmon chose to return Alphin’s affection; Alder was enraged. He flung boulders at Alphin, who responded in kind, and the two giants fought until Alphin was struck by a large rock and killed. Grief stricken, Rimmon cast herself from an outcrop and died beside her lover.
(The pointer marks Alphin Pike. Alderman’s Hill is north of the reservoir.)
This folktale could be rooted in the conflicts between Celts and advancing Anglian settlers during the post-Roman centuries. The giants may represent opposing armies occupying the respective peaks and Rimmon was the land over which they were fighting. ‘Alderman’ is a Germanic name but ‘Alphin’ could be Celtic. The legend about the battle of Win Hill and Lose Hill above Hope and Edale is believed to be a similar historical folk memory.
