Yuri Dolgorukiy
Daniel is mentioned in the "Simeonovskaya Chronicle" (late 15th century), year 1387, in connection to some priest who was exiled to the Lake Lacha by Yuri Dolgorukiy "same place as Daniel the Exile"; yet nothing is known about Daniel himself, only that he didn't belong to the ruling class and that he had been previously exiled after falling out of favour with the prince. Fyodor Buslaev suggested that he was the son of one of the prince's slaves, Mikhail Tikhomirov concluded that Daniel was an artisan, while Dmitry Likhachov indicated that he belonged to intelligentsia and served as a "milostnik" (prince's personal servant, a position similar to ministerialis).
