Urda, Verdandi, and Skulda
The three Nornir (Past, Present, and Future) who dwell in a beautiful hall below the ash-tree Yggdrasil'. Their employment is to engrave on a shield the destiny of man. (Scandinavian mythology.)
Urd (Past) takes the threads from Verdandi (Present), and Verdandi takes them from Skuld (Future). “What is that which was to-morrow and will be yesterday? ” Verdandi stands between Skuld (to-morrow) and Urd (yesterday).
