According to a later addition to the history of the late-11th-century
Byzantine historian
John Skylitzes, Agatha was a captive from
Larissa, and the daughter of the magnate of
Dyrrhachium,
John Chryselios. Skylitzes explicitly refers to her as the mother of Samuel's heir
Gavril Radomir, which means that she was probably Samuel's wife. On the other hand, Skylitzes later mentions that Gavril Radomir himself also took a beautiful captive, named
Irene, from Larissa as his wife. According to the editors of the
Prosopographie der mittelbyzantinischen Zeit, this may have been a source of confusion for a later copyist, and Agatha's real origin was not Larissa, but Dyrrhachium. According to the same work, it is likely that she had died by ca. 998, when her father surrendered Dyrrhachium to the Byzantine emperor
Basil II. Only two of Samuel's and Agatha's children are definitely known by name: Gavril Radomir and
Miroslava. Two further, unnamed, daughters are mentioned in 1018, while Samuel is also recorded as having had a bastard son. Agatha is one of the central characters in
Dimitar Talev's novel
Samuil. ==References==
