[6] When Henry VIII gave the lands of the dissolved monastery of Christ Church to Canterbury Cathedral, he declared that he made this donation “in order that charity to the poor, the reparation of roads and bridges, and other pious offices of all kinds should multiply and spread afar.” Elton, “Tenures of Kent,” London, 1867, p. 21. The gift is made “in liberam, puram et perpetuam eleemosynam.” This pious character was long continued: “As late as the period of the Commonwealth land and money devoted to the maintenance of bridges and causeys were definitely included among the charitable uses which were to be unaffected by the sequestration of Bishops’ land and other ecclesiastical revenues.” C. T. Flower, “Public Works in Mediæval Law,” Selden Society, 1905, i. p. xxi. [7] Thorold Rogers, “History of Agriculture and Prices in England,” Oxford, 1866, vol. i. p. 138. [8] See “Recherches historiques sur les congrégations hospitalières des frères pontifes,” by M. Grégoire, late Bishop of Blois. Paris, 1818. [9] This practice was inherited from the Roman builders, whose formularies continued to be transcribed throughout the middle ages. See Victor Mortet: “Un Formulaire du VIII^e siécle pour les fondations d’édifices et de ponts d’après des sources d’origine antique,” in “Bulletin monumental . . . de la Société française d’Archéologie,” vol. 71, 1907, p. 443. The brief chapter in the “Mappæ Clavicula” (still copied in the twelfth century), entitled “De fabrica in aqua,” recommends that, “Si fabricam in aqua necesse fuerit erigere, facis arcam triangulam,” _arca_ meaning _caisson_. In this we see, Mr. Mortet writes, “la disposition venue de l’antiquité, transmise et maintenue au moyen-âge, de la forme prismatique triangulaire des avant-becs des ponts” (p. 461). This characteristic was conspicuous, _e.g._ in the Avignon and London bridges (see the picture, p. 45) as well as in the famous Roman Pont du Gard. [10] On French mediæval bridges still in existence, their dates, modes of construction, crosses and chapels, see C. Enlart, “Manuel d’Archéologie Française,” Paris, 1902, ff. vol. ii. p. 264.

The work was apparently in progress in 1374, since we find, on the 15th of September of that year, an order to deliver to the same “trois cheisnes covenables” from Okeden forest. _Ibid._, p. 240.
