He lived in the reign of King Philip III of France (1245-1285), a time when the population of Paris was growing fast, requiring construction of a succession of enclosing walls ringing the city.
A minor work of great importance for its portrayal of the Paris of the period, Dit was first published in 1754 by abbé Lebeuf [fr], who discovered the manuscript in Dijon in 1754.The reference version was produced by Edgar Mareuse [fr] in 1875 after carefully reviewing the text against the manuscript preserved in the Bibliotheque nationale de France, and enriching it with notes, a glossary and preface.
[1] A long poem of 554 verses of eight syllables in an AABB rhyme scheme, Dit enumerates the streets of Paris, approaching them through the neighborhoods which then made up the capital: to the north the Rive Droite (right bank), Outre Grand-Pont ("Beyond Great Bridge"), also called the City, to the south the Left Bank, Outre-Petit-Pont ("Beyond Little Bridge"), also known as the University, and on the island, Île de la Cité, the cradle of Paris.
Guillot offers tasty descriptions for each of the 310 streets of Paris of the time, small scenes in few words, used like brush strokes to show the sellers of wheat and cloth, the butchers, tailors, armourers and goldsmiths, and even the prostitutes and footpads.
In the history of literature, the perambulations of Guillot, who takes his readers into the streets of the great Parisian labyrinth, foreshadow the genre of the Parisian urban stroll, which reached its apogee in the 19th century in the writings of Gérard de Nerval such as Nuits d'octobre (October Nights) and Mémoires d'un Parisen (Memoirs of a Parisian), as well as in Charles Baudelaire's Fleurs du mal and Spleen de Paris (Petits poèmes en prose).
