A historical mural by Ford Madox Brown depicting General Agricola supervising the construction of the Roman fort at Manchester in A.D. 80.

Ford Madox Brown produced this work as the first in a series of twelve murals for the Great Hall of Manchester Town Hall. The scene depicts the Roman general Agricola supervising the construction of a fort at Mancenion, the Roman name for Manchester, in A.D. 80. Brown used the Gambier Parry process, a method of spirit fresco painting, to ensure the durability of the murals in the damp climate of northern England. This technique involved mixing pigments with wax and resin. The composition focuses on Agricola, who stands in the centre wearing a red cloak and a gilded helmet. He holds a scroll containing the architectural plans for the fort. Beside him, his wife and daughter observe the progress. The daughter wears a hooded cloak, shielding her from the wind. In the background, Roman soldiers and British captives labour to build the stone walls. Brown includes specific historical details, such as the legionary standards and the leather armour of the workers. A centurion stands nearby, holding a vine staff as a symbol of his rank. Brown avoided idealised depictions of history. He chose instead to show the physical effort and the mundane aspects of construction. The figures are muscular and their poses are strained. The palette consists of earthy reds and ochres alongside blue tones, which contrast with the pale skin of the Roman family. This mural is a record of Brown's interest in local history and his desire to create public art that documented the origins of the city. The artist conducted extensive research into Roman military dress and engineering to achieve accuracy. He even included a small detail of a soldier carving an inscription into a stone block. The work reflects the Victorian interest in the Roman occupation of Britain as a precursor to their own empire.
