Pavan or Pavin.
Every pavan has its galliard (Spanish). Every sage has his moments of folly. Every white must have its black, and every sweet its sour. The pavan was a stately Spanish dance, in which the ladies and gentlemen stalked like peacocks (Latin, pavones), the gentlemen with their long robes of office, and the ladies with trains like peacocks tails. The pavan, like the minuet, ended with a quick movement called the galliard, a sort of gavotte.
