Jerome, Saint. [Letter to Marcella, 384 (3)] in Sancti Eusebii Hieronymi Epistulae ep.38

[Letter from Jerome to Marcella]
After comparing her suffering and testing to major biblical figures, Jerome describes Christ's appearance to call the widow Blesilla to him in her last illness, and defends the ascetic life she had espoused. Blesilla was the daughter of Paula, close friend and religious associate of Jerome and Marcella, and she was the widow of Furius whose sister Furia also corresponded with Jerome (, ep.54). Blesilla's death was attributed by Jerome's enemies to excessive ascetic practices, and the anti-monastic outcry drove Jerome to leave Rome.
