This intricate bronze situla is of slightly waisted cylindrical form with a rounded nipple base set in the centre of a repoussé rosette. The body is decorated with a procession of votaries walking in profile. The two figures with long hair and short-sleeved belted dresses may possibly be female. A shorter bearded male behind wears a ribbed conical hat and all three figures have their hands outstretched towards an altar. Behind this stands a tall bearded male holding a sceptre and wearing a large domed hat and a long skirt with punched decoration. The figurative scene is bordered above and below by a band of guilloche decoration.
