Like Nilus the Younger, Bartholomew was of Greek heritage.
He was also a personal disciple of the founder of the abbey Nilus the Younger.
When he succeeded Nilus as abbot, he supervised the completion of the abbey, of which he is considered the second founder.
Bartholomew the Younger was also a hymn-writer and noted calligrapher like his teacher.
He is also described as having a very sympathetic nature, and being unable to see anyone suffer without giving that party comfort.
