The poem that Richard Maidstone wrote on the metropolitan crisis of 1392 reports information about the royal entry that concluded the crisis in greater detail than any other source. The poem is not primarily a report, however; like Maidstone’s other writings, it is above all an ideologically driven literary intervention, produced at a particular moment, addressing a particular political circumstance. . . . Maidstone’s Concordia shows Anglo-Latin poetry, on a specific occasion, in the process of making itself a public poetry a broadly appealing, flexible, legible medium for addressing public issues.
