Prvotni natpis posvećen je božanskom Augustu i božici Romi, a potječe iz vremena cara Tiberija (14.-37. g.). Pisan je besprijekornom rimskom kapitalom, kakva odlikuje službene natpise postavljene od strane grada, gradske uprave ili neke institucije.
Drugi natpis na stražnjoj strani žrtvenika posvećen je zaštitniku mjesta, a nastao je po svemu sudeći nedugo nakon prvoga. Privatnog je provincijalno-lokalnog karaktera, a odlikuje se lošije izvedenom kapitalom u odnosu na prvi natpis. Dala ga je isklesati ilirka liburnskog podrijetla. Zavjetodavka je natpisom izrazila svoje duboko poštivanje carskog imena i carske ličnosti, povezala dva natpisa i dala do znanja da ne prisvaja aru, nego je naknadno posvećuje još jednom božanstvu, Geniju mjesta.
Zajedno s mramornim portretom Tiberija žrtvenik je pripadao svetištu (augusteum), hramu ili nekom javnom prostoru, posvećenom carevima i službenim božanstvima Romi i geniju mjesta (Oneuma).
Altar with two inscriptions, Omiš – Baučići, 1st C
The original inscription is dedicated to Divus Augustus and the goddess Roma, dating from the time of Emperor Tiberius (14-37). It is written in impeccable Roman capital letters, typical of official inscriptions erected by the city, city administration or an institution. The second inscription on the back of the altar is dedicated to the patron saint of the locality, and was, apparently, created shortly after the first. It is of private, provincial and local character, in poorly executed capitals, when compared against the first inscription. It was commissioned by an Illyrian woman of Liburnian origin, to express her deepest respect for the imperial name and person. The two inscriptions are interconnected, and the dedicator made it known that she made no claim of the altar, but rather dedicated it to another deity, the genius of the locality (genius loci).
Along with the marble portrait of Tiberius, the altar belonged to a sanctuary (augusteum), temple or another public space, dedicated to emperors and official deities Roma and the genius of the locality (Oneum).
