[442] Violet-le-Duc (Vol. IV, pp. 75-77) calls attention to the architectural refinements in this church, mentioning the use of arches flattened on their inner face and curved on the outer between the apse and triforium. It is also interesting to note that here as in Saint Remi the vault of the triforium differs from that of the ambulatory proper. The arrangement at Saint Remi has been described, that at Chalons consists of a simple four-part vault of trapezoidal form with outer and inner sides curved. [443] Examples at Strassburg, Cath., Neubourg (Eure), ch. (irregular type of ch. with central pier and triangular apse. See plan in Enlart, I, p. 590, Fig. 317) and Tewkesbury Abbey (here even the triangular bays open into chapels). See also Cléry (Loiret) (fifteenth century) (plan in Baudot and Perrault-Dabot, III, pl. 60). [444] Plan in Caumont, p. 396. [445] Examples not mentioned include, Beeskow; Keisheim; Stargarde, Johanniskirche (slightly elaborated); Treptow (considerably elaborated); Worms, Liebfrauenkirche; Arles, Saint Trophime, etc. [446] Plan in Gaudet, III, p. 247, Fig. 1108. [447] Plan in Gaudet, III, p. 240, Fig. 1104. [448] These two churches not only show the vault with simple added ribs but the last named is most interesting as showing an ambulatory equal in height to the apse, a most unusual arrangement. [449] This church also presents certain changes in the arrangement of the ribs but these are unimportant. [450] See also Kuttenberg. [451] A similar plan on a smaller scale and with only two side chapels occurs at Ville-neuve-le-Comte (Seine-et-Marne) (plan in Enlart, I, p. 485, Fig. 232) and the same arrangement in churches with central plan appears at Trier in the Liebfrauenkirche while other examples include Lisseweghe; Toul, Saint Gengoulf; Xant; Oppenheim; Ludinghausen; Anclam; Lübeck, Saint Jakob; Lagny (Seine-et-Marne) (illustrated in Lenoir, Part II, p. 207) and Kaschau (Hungary) (illustrated in Lenoir, Part II, p. 208). See also Enlart, I, p. 485, note 2. [452] Baudot and Perrault-Dabot, V, pl. 79. [453] Such chapels were frequently omitted all through both the Romanesque and Gothic periods even in churches with an ambulatory and were not therefore established parts of the church plan. For examples of such chapels see Enlart, I, p. 228 note 2 and p. 485 note 3 and Lasteyrie, p. 297. [454] For discussion of prototypes see Lasteyrie, pp. 187, 188.
