Wipo's most well-known work is the
Gesta Chuonradi II imperatoris (The Deeds of Emperor Conrad II), "the major and almost the sole nonofficial source for [Conrad's] reign" and an important source for the developing ideology of "pontifical kingship" which would culminate in the
Investiture Controversy under Conrad's grandson
Henry IV. Wipo presented this work to Conrad's son
Henry III in 1046, shortly after Henry was crowned Emperor. The text opens with a letter to Henry III and a prologue. In the prologue, written before 1046, the work is presented as a pair of biographies, of Conrad and Henry. In the letter, written after 1046, the life of Conrad is presented as an independent work. The narrative opens with Conrad's election in 1024 and continues through his reign in an annalistic format, concluding with his death in 1039. Wipo's main source was his own memory and oral reports from other members of the court, but he also employed a chronicle written at the
Reichenau Abbey. Wipo strews short snatches of
hexameter poetry throughout the work, and appends a nine verse
canticle in
rhymed hexameters, which he wrote at the time of Conrad's death at the end of the biography. , subject of Wipo's
Gesta Chuonradi II imperatoris The opening letter and prologue claim that the work was intended to provide an account of an exemplary contemporary Christian prince, as a counterpoint to the Biblical kings of the Old Testament and the pagan rulers known from Classical literature. Both the Vulgate text of the Bible and Classical authors, especially
Sallust and
Macrobius' commentary on the
Dream of Scipio, are frequently alluded to in the text. Wipo generally presents Conrad in very positive terms, sometimes modifying the facts in order to make Conrad a better exemplar. However, he declares himself willing to criticise Conrad for errors, and occasionally does so. Most biographies in Wipo's time were lives of saints or of kings presented as saintly figures, so the decision to write about Conrad as a layman was an innovative one.
Karl F. Morrison characterises the work as "an honest if not penetrating annalistic account of a secular ruler in unecclesiastical, unsanctimonious terms." The work was not widely read in the Middle Ages and now survives in only a single manuscript held in the in
