One of the most puzzling of Lydgate's works is Serpent of Division, a short prose tract written in 1422, recounting the life of Caesar and describing the terrible consequences of political and social division. At first glance, the text appears to be an ideal object for historical analysis; written at a critical moment in Lancastrian history just after the death of Henry V, it narrates the rise and fall of a brilliant military leader as a warning to “lordes and prynces of renowne” of the “irrecuperable harmes” (66, line 19, line 2) of political and social division. The allegorical logic of the text is difficult to ignore, as is Lydgate's insistence on a resolutely moral reading of both “division” and Caesar himself. Indeed, a simple historical reading arguing that Lydgate uses the exemplum as a means of negotiating the crisis produced by the death of the monarch seems to be what the text itself demands.
