English poem
The fowrthe artycul thys moste be
by William Langland (1332–1386)
The fowrthe artycul thys moste be, That the mayster hym wel be-se That he no bondemon prentys make, Ny for no covetyse do hym take; For the lord that he ys bonde to, May fache the prentes whersever he go. Early History of Freemasonry in England, p. 14.
