In 1970, Burgess was approached by the Italian producer, Vincenzo Labella, to write the film script for a television mini-series about Moses to be co-produced by Radiotelevisione Italiana (RAI) and Lew Grade. Burt Lancaster would star as Moses, with Anthony Quayle portraying Aaron. In autumn 1972, Burgess began work on a verse novel, later published as Moses: A Narrative, from which he fashioned scripts for the six hour-long episodes of Moses the Lawgiver, finishing them in Rome the following summer.
Upon completing the script, Burgess composed a score for Moses the Lawgiver. The Moses score was, however, unsolicited and unexpected by the producer, who turned down Burgess's request to compose the music for the entire miniseries. Labella approached Ennio Morricone to write the score instead.
This series consists of drafts of Moses: A Narrative, a treatment and character list for the television series, outlines for various episodes, and drafts of the screenplay in English and Italian.
