I think there was supposed to be a sword, but as it is St. George is whaling on the dragon with his righteous fist.
August Kiss, 1855.

Fun facts: Saint George was possibly a Greek soldier from Cappadocia (Northern Syria) who died in the Diocletian persecutions around 303 AD. There are no extent records of his existence.

Somehow by the Golden Legends of the 1260s, St. George got transferred to Libya. In it he comes across a small kingdom where a dragon had poisoned the local spring. To keep the dragon happy, the inhabitants had fed it sheep, then men, then children, chosen by lot. The day St. George passed by, the princess had been selected by the lot, and had been dressed as a bride to be sacrificed. St. George makes a sign of the cross, then charged it, wounding the dragon. He thereupon asked the princess to throw him her girdle, which he used to place around the dragon's neck. With that, the dragon meekly submitted, and with St. George, was led by the princess back to the city. In the city, the inhabitants were in panic, until St. George offered to kill the dragon in exchange for the inhabitants converting to Christianity, which they did (15000 of them). St. George then decapitated the dragon.

St. George is one of the most popular saints known, and is the patron saint of England, Georgia, and Catalonia. Everyone it seems from Portugal to Ethiopia to Russia, depicts him spearing the dragon.
