The study focuses on two objectives. The first is to divide the human activity traces from the natural erosion. On the other hand, we want to decide if the inscriptions came through the use of some antique tools or some recent ones, steels especially. The locations by where we taken the samples, are: the altar; profile of human shape; superior opened vertically well; inscription on opposite wall; recess. 1. Introduction This paper presents the results of an application of AAS to the study of Pre-Roman inscriptions from the ancient site of Sinca Veche, Brasov county-Romania. The temple of Sinca Veche, determined some series of contradictory discussions in Archaeology and History fields, both by Romanian and foreign specialists. Some of them consider the origin of the temple is from the Pelasges culture, a Pre-Dacian civilization. Even if in the 17 th century there were a lot of shelters for monks, the truth is that the signs places are not related with Christian symbols. One of the most important factors in the scientific examination of antiquities is the application of AAS analysis of the interior composition of an object with ancient symbolic representations. It is in the speed of analysis that AAS has a clear advantage. By example, it is common for NAA to require one or two reactor irradiations followed by cooling periods and then at least 100 min of counting time, whereas, AAS analysis of a given sample, can be performed in about 10-15 min. In the same time, we choose this method because we concentrate in finding a very small concentration for elements from the tools used in inscripting the religious signs end drawings. After that, we made an observation of the results comparing the AAS given concentrations with geological catalogues from the soil around the obtaining samples. The study focuses on two objectives. The first is to divide the human activity traces from the natural erosion. On the other hand, we want to decide if the inscriptions came through the use of some antique tools or some recent ones, steels especially. The locations by where we taken the samples, are: 1- the altar; 2- profile of human shape; 3-superior opened vertically well; 4- inscription on opposite wall; 5- recess. 2. Experimental There are five different places from where the samples were taken and these elements were observed by AAS method in order to determine the metal concentration of traces. For a proper concentrations determination of the geological solid sample those were taken for a preliminary process of mineralization. The device was given from HACH and it’s made up in order to realize a complete mineralization in about 3-12 min with a low consume of reactive. The samples were
