"The royal household ordinances of 1455 specified four minstrels with another nine minstrels coming to Court
at the principal feasts of the year. The Liber Niger of Edward IV’s reign, (ordinances governing the household),
required two minstrels to remain in Court at all times, with the addition of two string-minstrels if the king wished:
the other minstrels were required to come to Court for the five principal feasts and to leave Court the day after
each feast was finished."
