Charles Eliot,
Hinduism and Buddhism, An Historical Sketch…
“ The text of the Pâtimokkha is in the Vinaya combined with a very ancient commentary called the Sutta-vibhanga. The Vinaya also contains two treatises known collectively as the Khandakas but more frequently cited by their separate names as Mahâvagga and Cullavagga. The first deals with such topics as the rules for admission to the order, and observance of fast days, and in treating of each rule it describes the occasion on which the Buddha made it and to some extent follows the order of chronology. For some parts of the master's life it is almost a biography. ”
