According to the bibliography in the territory of Salona (Roman province of Dalmatia), two fragmentary statues of Mater Magna with an object similar to cista mystica were found. This is an ‘atypical’ attribute, at least regarding to the depictions of the goddess in sculpture. More frequently, it appears in the images related to the ministers of the cult, the priests of the Phrygian and Roman tradition. The contribution examines the significance of cista mystica within the cult of Mater Magna and Attis as well as the question of identification and significance of this attribute in statues from Salona.
