[174] We have seen before that Eadmer mentions the malaria in Rome as early as the twelfth century. (Historiæ Novor., lib. ii. ad calcem S. Anselmi operum, p. 51, D. Lut. Par. 1675, fol.) In the following century, the author of “Sir Bevis of Southampton” gives a strange account of the fevers arising from the Pontine Marshes into the Campagna di Roma. There were, says he, two dragons there; one having fled to Toscan [Tusculum?],— “That other dragoun ’is flight nome (took) To Seinte Peter ’is brige of Rome: Thar he schel leggen ai (lay for ever) Til hit come domesdai; And everi seve yer ones, Whan the dragoun moweth (moves) ’is bones, Thanne cometh a roke (reke, smoke) & a stink Out of the water, under the brink, Than men therof taketh the fevere, That never after mai he kever (recover); And who that n’el nought leve (believe) me, Wite (know, inquire) al pilgrimes that ther hath be; For thai can tell yow, I wis, Of that dragoun how it is.” (Weber, “Metrical Romances,” &c., vol. iii. p. 315. Edinburgh, 1810, 12mo.) [175] The fragment of an inscription relating to this aqueduct was found near Gabii, and is described by E. Q. Visconti in his _Monumenti Gabini_, Roma, 1797, 8vo. maj., p. 14. IMP. CAESAR DIVI TRAiani (Parthici filius Trajanus Hadrianus) AVG. PONTIF[ex Maximus] AQVAE DVCTVM GABINIS . . . QVAM . . . . . The second line appears to be an interpolation of the editor, but this is not material. The aqueduct begun by Nerva was not finished till the time of Hadrian. The aqueduct of Gregory XIII. and Sixtus V. (Felice) (A.D. 1572-1590) receives the water of this aqueduct, but at Colonna other springs are collected and added to it; this was the work of Fontana. [176] The Torre Pignattara is so called from the earthenware pots (_pignatte_) of which the vault was built. Other remains of buildings of importance have been found near the Mausoleum of S. Helena, and there is some reason to believe that another imperial villa was situated there during the first three centuries. [177] Some say the popular name is _Torre de Scavi_, or of the excavations from some great works of excavation made there in the twelfth century. [178] Note f, p. 88. “Aquarum ductus etiam infinitas hoc nomine (Hadriani) nuncupavit.” (Spartianus in Hadriano, c. 20.) [179] It is immediately opposite to the Palatine, and there is a remarkably fine view from the portion of the _specus_ that remains, the vault of which has been removed, and it is used as a terrace.
