‘Wider than the realm of England’: the Hosack family heritage, Atlantic slavery and casting Mary, Queen of Scots for the nation

In 1871 the Scottish-born magistrate John Hosack (1809–87) was described as ‘the chivalrous and most recent defender’ of Mary, Queen of Scots. After writing a popular historical account of her life, he had presented a plaster cast bust of her Westminster effigy to London’s National Portrait Gallery, which it then used to create an electrotype sculpture with the help of Elkington & Co. This article interrogates the ‘value’ of this sculpture as a cultural heritage object by retracing its history. It places Hosack’s desire to replicate and commemorate Scottish heritage alongside his family ties to Jamaica, including the parallel life of his half-brother William and the wealth John derived from his father’s sugar profits, which relied on African enslavement. It argues the importance of understanding how such legacies enabled individuals to participate in cultural philanthropy in the Victorian period, which simultaneously distanced them from their Atlantic pasts. It also considers how, in its transformation into an electrotype, Hosack’s cast became part of a wider effort by museums and galleries to replicate national heritage using manufacturing methods indebted to the industrial economy intertwined with the British Empire. Sculpture offered a powerful medium through which to fortify national history, but its commemorative capacity can, and should, be unpicked to better understand British legacies of enslavement and colonialism.
