Humility of Heart was written by Father Cajetan Mary da Bergamo a Capuchin priest in 1739. The work instantly caught fire among the religious but remained obscure until it was translated from Italian into English by Herbert Cardinal Vaughan of Westminster. Unbeknown to every subsequent re-publisher of Vaughan's translation was that Vaughan died before finishing the work, leaving the final section of the work untranslated until now.
