The essay offers a contextualization of one of the three annals written in Bari between the 11th and 12th centuries: the Anonymous’ Chronicle, which hasn’t a manuscript tradition. In the first part of the essay, by analyzing the contents, style, and main themes, multiple sections of the text, written at different times, are identified. The last part of the essay highlights the relationship between the final section of the Anonymous and the rise of Prince Grimoald in the city (1118). The Anonymous provides an opportunity to investigate the relationship between the construction, management, and sharing of memory and the political dimension.
