During the archaeological excavations of the Tetraconch Church of the Saints Sergios, Bacchos and Leontios in Bosra (Syria), collaboration between University of Bologna (Director Prof. R. Farioli Campanati, Responsible of excavation PhD G. Bucci) and DGAM Syria, Direction Générale des Antiquités et de Musée de Syrie, Bosra Department (Arch. Wafa. Al Oude and Fayez Al Douz) under the High Patronage of the Italian Foreign Ministry, we discovered many findings belonging to Late Antique suspending lights: polykandela, polyangistra and lychniai ualai. We collected a big bronze discs which bears a geometric decoration of interlacing flat circles with three holes for hanging suspending hooks, a decorative disc with cross, glass beakers, stems and suspending devices of different typologies, including chains, hooks, rings, bars. The chronology of our evidences is attested mainly between the sixth and the seventh century AD. Thanks to a peculiar documentation of the stratigraphic excavations, a detailed catalogation of the artefacts, and a wide research about suspending light devices between Late Antique and Middle Age in the Near East, following the indication of the iconographical support of the Syrian Floor Mosaics representations, we completed a reconstruction of the lighting system of the Tetraconch Church. Here we would like to introduce some unpublished findings and our last studies about suspending lights found in Bosra.
