In 1162, Peter replaced the deceased Count Sylvester of Marsico in the triumvirate of officials—including Matthew of Ajello and Richard Palmer—in whom the king had confided the administration of the realm since the assassination of his prime minister, Maio of Bari, in 1160.
Sylvester of Marsico died at the same time and Matthew of Ajello and the caïd Peter replaced him and Aristippus in the "triumvirate."
But Stephen's greatest opponents was Matthew of Ajello, a notary whom he had offended the year previous.
When in 1162 William was besieging Salerno, Sylvester and Palmer interceded on behalf of the Salernitan notary Matthew of Ajello to prevent a sack.
One of the chief authors of the treaty as it stands was a young notary named Matthew of Ajello, later of much fame in Sicily.
In 1174, the first fruits of a plan of the king and the vice-chancellor, Matthew of Ajello, began to flower.
