Pacheco relates a remarkable effect produced by a picture from the pencil of Methodius, who resided at Constantinople about 854. He was invited to Nicopolis by Bogoris, king of the Bulgarians, to decorate a banqueting-hall in his palace. That prince left the choice of his subject to the artist, limiting him to those of a tragic or terrible character. The sister of Bogoris, during a long captivity at Constantinople, had become a convert to the Greek church, and greatly desired that her brother should renounce paganism; therefore it was probably at her instance, in this case, that Methodius painted the Last Judgment. He succeeded in depicting the glories of the blessed and the pains of the damned in such a fearful manner, that the heathen king was induced in his terror to send for a Bishop, and signify his willingness to unite with the Greek church; and the whole Bulgarian nation soon followed his example.
