This is a well knowns type of gold brooch (finula), popular in Etruria towards the end of the sixth century BC. The type developed from the basic bow fibula, which had already been popular in Italy for several hundred years. The once simple bow-shape has been replaced by the body of an animal.
This brooch is decorated with a chimaera (a beast composed of parts of various animals), with the head and body of a lion with wings and a serpent-head tail. The beast on this brooch opens its jaws. Behind is a bird surrounded by two lions.
The brooch is made from gold sheet with the animals made in two halves which have been stamped into a mould and soldered together lengthwisedown their body.
