A tombstone of a seven-year-old Roman boy Gaius Laberius holding a ball with hexagons joined in the manner of a net-like ornament. The symbol of a real leather ball, it is considered firm evidence that football in Europe was first played in the Cetinska Krajina Region. It was found in the Tilurium site, in the locality of Gardun, and dates back to the 2nd century. Today the tombstone is built into the front wall of the Perković family-owned stone building in Vrlička ulica at number 10 in Sinj. Made of limestone, the monument is 113 centimetres high and 46 centimetres wide. At the bottom there is a two-part inscription, the first part of the inscription being in a well-defined frame and informing about Gaius Laberius, whereas the second part is an inscription by an unkonown author dedicated to the boy. The central part is a round medallion framed with ornaments, bearing a portrait of the boy who holds the ball in his right hand. At the top of the monument there is a frieze showing a kantharos (a large two-handle vase), a dolphin and the head of Medusa (in ancient mythology, the personification of evil) and a triangular gable with acroteria (plastic ornaments of tops and corners) in the shape of lion’s paws. The head of Atis is sculptured in the triangular gable. Even though football was played at Gardun among Roman soldiers and sons of the rich, originally the game was Illyrian and the Delmates had played it long before the Roman troops arrived.
