The sica was a short sword or large dagger of ancient Illyrians, Thracians and Dacians, used in Ancient Rome too, originating in the Halstatt culture. It was originally depicted as a curved sword (see the Zliten mosaic as well as numerous oil lamps), with a blade about 16–18 inches long (40–45 cm) and many examples have been found in what are today Albania, Romania, Bosnia, Bulgaria and Serbia. It is also depicted on Trajan’s Column; notably the Dacian king Decebalus is depicted committing suicide with one.
