The historical region of Epirus is generally regarded as extending from the northern end of the Ceraunian mountains (modern Llogara in Albania), located just south of the Bay of Aulon (modern Vlorë), to the Ambracian Gulf (or Gulf of Arta) in Greece [REF].
The definition of Epirus has changed over time, such that modern administrative boundaries do not correspond to the boundaries of ancient Epirus.
