Coppelius and Spalanzani's collaborative and conflictual relationship

The relationship between the barrister Coppelius and the physics professor Spalanzani is one of the story's most sinister and revealing alliances, a partnership forged in the hidden workshop of Nathaniel's father and culminating in a spectacular, bloody feud over the automaton Olympia. Their bond is defined by a shared, obsessive labor—the construction of a lifelike mechanical woman—and a mutual contempt that erupts into physical violence when their collaboration collapses. The relationship exposes the dark, material underpinnings of the tale's supernatural horrors, revealing that the Sandman and the scientist are not opposing forces but co-conspirators in a project that blurs the line between creation and exploitation.

Origins and Secret Collaboration

The earliest evidence of the Coppelius-Spalanzani connection lies in the hidden laboratory of Nathaniel's father. As a child, Nathaniel witnessed Coppelius and his father working together at a small hearth, where Coppelius swung red-hot tongs and hammered a bright, flickering mass of ore, while human faces without eyes appeared in the vapour. Coppelius's cry of "Eyes out, eyes out!" and his attempt to seize Nathaniel's eyes, thwarted only by the father's plea, establish that the pair's alchemical or mechanical experiments were already concerned with ocular mechanisms. This early scene foreshadows the later revelation that Spalanzani, too, is a maker of automatons, and that Coppelius has been a long-term supplier of the crucial component: eyes. The partnership is thus rooted in a shared, secretive craft that predates the story's main events and involves the exploitation of Nathaniel's family.

The Automaton Project and Its Division of Labor

Years later, the collaboration resurfaces in the figure of Giuseppe Coppola, the barometer salesman who is revealed to be Coppelius in disguise. Coppola sells Nathaniel a looking-glass that allows him to see Olympia, Spalanzani's daughter, with unprecedented clarity, sparking Nathaniel's fatal obsession. The true nature of the partnership is exposed during the violent confrontation in Spalanzani's study. As the two men struggle over Olympia's body, Spalanzani screams, "Did I put my life and limb on the line for that?" and Coppola retorts, "Ha ha ha ha! – that was not our arrangement – it was me, me who made the eyes!" Spalanzani counters, "And I the mechanical clockwork!" This exchange reveals a precise division of labor: Coppola crafted Olympia's eyes, while Spalanzani built her clockwork, speech, and step. The automaton is thus the product of a joint venture, with each man claiming credit for a vital part of her illusion of life.

The Violent Rupture and Its Aftermath

The partnership ends in a savage, public fight. Nathaniel, drawn by the noise, finds Spalanzani and Coppola tugging and tearing at Olympia's figure, "furiously fighting for possession." Coppola, with a mighty burst of strength, yanks the figure free, swings it, and strikes Nathaniel with it, then flees down the steps, the automaton's feet banging with a wooden thud. Spalanzani, bleeding from glass shards, cries out, "Coppelius has robbed me of my finest automaton – twenty years' work – life and limb invested – the clockwork – speech – step – all mine – the eyes – the eyes robbed from you." He then picks up a pair of bloody eyes from the floor and flings them at Nathaniel, triggering the young man's final descent into madness. The rupture is total: Coppola vanishes with the automaton's body, and Spalanzani, wounded and exposed, is forced to leave the university to escape a criminal investigation for fraud. Their collaboration, born in secrecy and sustained by mutual need, ends in mutual destruction, leaving only the wreckage of their creation and the shattered mind of the man who loved it.
