chainwork, a six-pronged piece of iron resembling a hayfork, and the helmet. As Bateman described it: Bateman closed his 1849 account of the excavation by noting the "particularly corrosive nature of the soil", which by 1861 he said "has generally been the case in tumuli in Derbyshire". He suggested that this was the result of "a mixing or tempering with some corrosive liquid; the result of which is the presence of thin ochrey veins in the earth, and the decomposition of nearly the whole of the human remains." Bateman's friend Llewellynn Jewitt, an artist and antiquarian who frequently accompanied Bateman on excavations, painted four watercolours of the finds, parts of which were included in Bateman's 1849 account. This was more than Jewitt produced for any other of their excavations, a mark of the importance that they assigned to the Benty Grange barrow. The helmet entered the extensive collection of Bateman, where it attracted interest. On 27 October 1848 he related his discoveries, including the helmet, to the British Archæological Association, and in 1855 it was catalogued along with other objects from the Benty Grange barrow. In 1861 Bateman died at 39, and in 1876 his son, Thomas W. Bateman, loaned the objects to Sheffield. They were displayed at the Weston Park Museum through 1893, at which time the museum purchased objects, including the helmet, from the family; other pieces were dispersed elsewhere. As of 2021, the helmet remains in the collection of the museum. From 8 November 1991 to 8 March 1992 it joined the Coppergate helmet at the British Museum for The Making of England: Anglo-Saxon Art and Culture, AD 600–900. The Benty Grange barrow was designated a scheduled monument on 23 October 1970. The list entry notes that "[a]lthough the centre of Benty Grange [barrow] has been partially disturbed by excavation, the monument is otherwise undisturbed and retains significant archaeological remains." It goes on to note that further excavation would yield new information. The nearby farm was renovated between 2012 and 2014; as of 2021 it is rented out as a holiday cottage. Conservation In 1948, the helmet was brought to the British Museum to undergo cleaning and study. Permission to carry out the work had been requested the previous year, when Rupert Bruce-Mitford, recently returned from World War II service in the Royal Signals to an assistant keepership at the museum, spent time in Sheffield examining the
