One of the greater flamens was attached to the service of Quirinus, a second college of Salii founded in his honour, and a festival "Quirinalia" celebrated on the 17th of February, the day of the supposed translation of Romulus to heaven.
Yet another fashion was that adopted by the flamens, who passed the right-hand portion of the toga over the right shoulder and arm and back over the left shoulder, so that it hung down in a curve over the front of the body; the upper edge was folded over.
The flamens are thus represented on the Ara Pacis Augustae.
The trabea, which in historical times was worn by the consuls when opening the temple of Janus, by the equites at their yearly inspection and on some other occasions, and by the Salii at their ritual dances, and had (according to tradition) formed the original costume of the augurs and flamens (who afterwards adopted the toga praetexta), was apparently a toga smaller in size than the ordinary civil dress, decorated with scarlet stripes (trabes).
These were the inauguration of the rex sacrorum and the flamens, and that abjuration of hereditary worship (detestatio sacrorum) which was made by a man who passed from his clan (gens) either by an act of adrogation (see Roman Law and Adoption) or by transition from the patrician to the plebeian order.
The flamens were subject to the pontifex maximus, and were consecrated to the service of some particular deity.
When the number of flamens was raised from three to fifteen, those already mentioned were entitled majores, in contradistinction to the other twelve, who were called minores, as connected with less important deities, and were chosen from the plebs.
Towards the end of the republic the number of the lesser flamens seems to have diminished.
The flamens were held to be elected for life, but they might be compelled to resign office for neglect of duty, or on the occurrence of some ill-omened event (such as the cap falling off the head) during the performance of their rites.
The characteristic dress of the flamens in general was the apex, a white conical cap, the laena or mantle, and a laurel wreath.
The main duty of the flamens was the offering of daily sacrifices; on the 1st of October the three major flamens drove to the Capitol and sacrificed to Fides Publica (the Honour of the People).
Some of the municipal towns in Italy had flamens as well as Rome.
We may mention, as distinct from the above, the flamen curialis, who assisted the curio, the priest who attended to the religious affairs of each curia; the flamens of various sacerdotal corporations, such as the Arval Brothers; the flamen Augustalis, who superintended the worship of the emperor in the provinces.
