The Twenty-Six Commandments or Irish Duelling Code (1777)
“ The challenger ought not to have challenged without receiving offence, and the challenged ought, if he gave offence, to have made an apology before he came on the ground; therefore children's play must be dishonourable on one side or the other, and is accordingly prohibited. XIII. Seconds are to be of equal rank in society with the principals they attend, inasmuch as a second may either choose or chance to become a principal and equality is indispensable. XIV. Challenges are never to be delivered at night, unless the party to be challenged intends leaving the place of offence before morning ”
