leaders of Miletus learned about this, they arrested him and sought advice from visiting Roman envoys on what to do with him; the envoys were contemptuous of the pretender and told the Miletans he was safe to release. He continued his travels through Ionia, meeting former acquaintances of Perseus and gaining an audience with Kallipa, a former concubine of Perseus who was now married to Athenaios, brother of the Pergamene king Attalus II Philadelphus. Being a Macedonian by birth, and due to her former connections to the Antigonids, she accepted his claim and agreed to help him, giving him money and slaves, and probably recommending that he travel to Thrace, where he would find a following. He was also received favourably in Byzantium. He finally arrived in Thrace, where he met Teres III, who had married the granddaughter of Perseus and was the son of Cotys IV, who had once been an ally of Perseus.

Anti-Roman sentiment was common in Macedon; the populace was obliging in overthrowing the old regime. Support for Andriscus was not uniform — there was significantly more hesitation among the gentry and upper classes, and somewhat more enthusiasm among the lower classes — but the popular mood was largely in his favour. His claims were bolstered by his correct prediction of the locations of two treasures, which he claimed were specified in the "sealed writing" that had been handed to his caretakers by Perseus, and had later been given to him. Even if there were apprehensions about the veracity of his claim, Niese notes that "one liked to believe what one wished; the re-establishment
