Theodore exercised a wide influence during the first year of his exile, primarily through a massive letter-writing campaign. Accordingly, he was transferred in 816 to Boneta, a fortress in the more remote Anatolic theme, whence he nevertheless remained abreast of developments in the capital and maintained a regular correspondence. This continued activity led to an imperial order that Theodore be whipped, which his captors however refused to carry out. In 817, Theodore wrote two letters to Pope Paschal I, which were co-signed by several fellow iconophile abbots, in the first requesting that he summon an anti-iconoclastic Synod; letters to the Patriarchs of Alexandria and Jerusalem, among other "foreign" clerics, followed. As a result, the emperor ordered at least once more that Theodore be flogged, and the command was this time carried out, with the result that Theodore became quite ill. After his recovery Theodore was moved to Smyrna. Early in 821, however, Leo V fell victim to a grisly murder at the altar of the Church of St. Stephen in the imperial palace; Theodore was released from exile shortly thereafter.
