Sica

The sica is a short sword or large dagger of ancient Illyrians, Thracians, and Dacians, it was also used in Ancient Rome. It is a shorter form of the falx, and the root of the word is the same as the modern sickle.^[1]

It was originally depicted as a curved sword (see the Zliten mosaic as well as numerous oil lamps) and many examples have been found in what are today Croatia, Albania, Bosnia and Herzegovina, Bulgaria, Serbia, and Romania. It is also depicted on Trajan's Column; notably the Dacian king Decebalus is depicted dying by suicide with one.
