More generally the size of the area is expressed, as in the following: IN FRONTE P[EDES] · IX IN AGRO P[EDES] · X; that is, “Frontage on the 60 road, nine feet; depth in the field, ten feet.” This area, small as it is, was designed for several families. The limited space occupied by the cinerary urns rendered this quite possible. Frequently, however, the size was much larger. An area one hundred and twenty-five feet square would be of very moderate extent. Horace mentions one one thousand feet by three hundred,[53] and sometimes they greatly exceed this, as one on the Via Labicana, five hundred by eighteen hundred feet, or over twenty English acres. There were also frequently _exhedræ_, or seats by the wayside, for passers-by, who were sometimes exhorted to pause and read the inscription, or to pour a libation for the dead, as in the following: SISTE VIATOR TV QVI VIA FLAMINIA TRANSIS, RESTA AC RELEGE--“Stop, traveller, who passest by on the Flaminian Way; pause and read, and read again!” MISCE BIBE DA MIHI--“Mix, drink, and give to me.” VIATORES SALVETE ET VALETE--“Travellers, hail and farewell.” These burial plots were incapable of alienation or transfer from the families for whom they were originally set apart; who are sometimes enumerated in the inscription, or more generally expressed by the formulæ, SIBI SVISQVE FECIT, SIBI ET POSTERIS SVIS, or with the addition, LIBERTIS LIBERTABVSQVE POSTERISQVE, that is, “He made this for himself and his family,” or “for himself and his descendants;” also “for his freedmen and freedwomen and their descendants.” Sometimes this limitation is plainly asserted to be, VT NE VNQVAM DE NOMINE FAMILIAE NOSTRAE HOC MONVMENTVM EXEAT--“That this monument 61 may not go out of the name of our family.” The cupidity of the inheritor of the estate is especially guarded against by the ever-recurring formula, H · M · H · N · S ·, that is, _Hoc monumentum hæredem non sequitur_--“This monument descends not to the heir.” Sometimes within a stately mausoleum reposed in solitary magnificence the dust of a single individual, who in sullen exclusiveness declares in his epitaph that he has no associate even in the grave, or that he made his tomb for himself alone--IN HOC MONVMENTO SOCIVM HABEO NVLLVM, or, HOC SOLO SIBI FECIT. The violation of the monument is earnestly deprecated in numerous inscriptions in some such terms as these: ROGO PER DEOS SVPEROS INFEROSQVE NE VELITIS OSSA MEA VIOLARE--“I beseech you, by the supernal and infernal gods, that you do not violate my bones.” Sometimes this petition is accompanied by an imprecation of divine vengeance if it should be neglected, as, QVI VIOLAVERIT DEOS SENTIAT IRATOS--“May he feel the wrath of the gods[54] who shall have violated [this tomb.]” Another invokes the fearful curse, QVISQVIS HOC SVSTVLERIT AVT LAESERIT VLTIMVS SVORVM MORIATVR[55]--“Whoever shall take away or injure this [tomb] let him die the last of his race.”
