The majority of the glass finds discovered during the excavations at the monastery of Olba consists of fragments belonging to lamps, goblets, and window panes that indicate the use of glass for illumination. In addition to these, fragments of bowls, plates, jars, or flasks were also recorded. As almost all the glass fragments were found within the earth fill, it is not possible to build a chronology through stratigraphy. The only location that gives numismatic evidence for dating is the stone basin. The densely corroded coins from the basin suggest a date starting from the sixth century AD. The overall study of the archaeological evidence from the monastery, as well as the typological research into the glass material, reveal that the glass finds belong to a period starting from the fifth century and ending in the seventh century AD.
