It is interesting to compare with this _carmen_ the prayers of the guild of brethren (_Attiedii_) at Iguvium; these are the best preserved of all old Italian prayers, and though not Roman, are the product of the same race. In the lustratio of the _arx_ (_Ocris Fisius_) of Iguvium we find three several deities invoked, with elaborate sacrificial ritual, at three gates, and a long prayer addressed to each deity, thrice repeated, as in the _Carmen Arvale_. It is to be said under the breath (_tacitus precator totum_, vi. A. 55), which was a common practice also at Rome, and is believed to be characteristic of the magical spell;[391] and except in the case of the first prayer, which is addressed to the chief deity Jupiter Grabovius, it is accompanied by some kind of dancing or rhythmical movement (_tripodatio_).[392] Thus in outward form this ritual seems to show but little advance on the Roman prayer of the Arvales, and indeed it may in substance go back to a time as remote as that in which the latter had its origin. But when we examine the matter of the prayer, we find that it is cast in the language of petition beyond all doubt--if it be rightly interpreted, as we may believe it is:-- "Te invocavi invoco divum Grabovium pro arce Fisia, pro urbe Iguvina, pro arcis nomine, pro urbis nomine: _volens sis, propitius sis_ arci Fisiae, urbi Iguvinae, arcis nomini, urbis nomini. Sancte, te invocavi invoco divum Grabovium. Sancti fiducia te invocavi invoco divum Grabovium. Dive Grabovie te hoc bove opimo piaculo pro arce Fisia, etc. Dive Grabovi, illius anni quiquomque in arce Fisia ignis ortus est, in urbe Iguvina ritus debiti omissi sunt, pro nihilo ducito. Dive Grabovi, quicquid tui sacrificii vitiatum est, peccatum est, peremptum est, fraudatum est, demptum est, tui sacrificii visum invisum vitium est, dive Grabovi, quicquid ius sit, hoc bove opimo piaculo piando.... Dive Grabovi, piato arcem Fisiam, piato urbem Iguvinam. Dive Grabovi, piato arcis Fisiae, urbis Iguvinae, nomen, magistratus, ritus, viros, pecora, fundos, fruges: piato, _esto volens propitius pace tua_ arci Fisiae, etc. Dive Grabovi, salvam servato arcem Fisiam salvam servato urbem Iguvinam .... Dive Grabovi, te hoc bove opimo piaculo pro arce Fisia, pro urbe Iguvina, pro arcis nomine, pro urbis nomine, Dive Grabovi, te invocavi."[393]
