Note 155 — ACTUS I, SCÆNA 1.[129]
Reading edition
When the combat was demanded and allowed, it was the custom for each party to take an oath to the following purport, viz., "that they had not brought into the lists other armour or weapon than was allowed, neither any engine, instrument, herbe, charm, or enchantment, and that neither of them should put affiance or trust in anything other than God and their own valours, as God and the holy Evangelists should help them."—Segar's "Honour Military, &c.," p. 134.
