In fact, there are three almost identical letters with the same initia and subject matter. The first is dated 15 July 1225, and was sent to the son of the king of Hungary; Regesta Honorii Papae III, ed. P. Pressuti, Rome 1888, ii. 350, no. 5560; Pott. 7443. The second bears the same date and was a copy of the first letter sent to the archbishop of Kolocsz: Regesta, ed. Pressuti, ii. 350, no. 5560; Pott. 7444 (this is the same letter as Pott. 6318). The third is a second copy, which was sent to the archbishop on 23 August 1225; Regesta, ed. Pressuti, ii. 361, no. 5611; Pott. 7466 (this is the same as Pott. 7835). The error in Regesta, ed. Pressuti, i. no. 2593, is noted in the Appendix of Agenda et Corrigenda, ii. 494, sub no. 2593, and 499, sub no. 5560. Intellecto (23 August 1225) is printed in full in Pontificia Commissio ad Redigendum, ‘Acta Romanorum Pontificum’, Fontes, Ser. in, vol. iii, Ada Honorii III et Gregorii IX, ed. A. L. Tàutu, Vatica n 1950, 188, doc. 143. I am indebted to Professor Ullmann for bringing this to my attention.

page 27 note 6 The Roman law allowed minors under the age of twenty-five to disaffirm or rescind disadvantageous contracts: D. 4. 4. 7. 1; D. 4. 4. 11. 4; D. 4. 4. 44; D. 4. 4. 49; Stein's Buckland, 721, 722. The age is twenty-one in the common law and the modern civil and canon laws: 2 Inst. 482, 483; 2 Williston on Contracts, 3rd ed. 1959, §§ 222–7; Planiol, i. §§ 1615–17, 1634, ii. §§ 1081 ff.; C. I. C, can. 88, § 1; Bouscaren, Ellis, Korth, Canon Law, 79. The king was twenty-four when he took the oath; thus, the pope is seen not to have applied the common law as he should have done but the civil law with which he was undoubtedly more familiar.
