graeffei quadratus

"The Red-Squared Slug; Triboniophorus graeffei var. quadratus - c. 1890," 2026

Glass Jar Specimen, Two Taxonomic Models (taxidermist unknown), and Archival Correspondence.

These objects once belonged to two nineteenth-century personal collections.

The handwritten letter and the wet specimen [an impaled slug preserved on a thorn of Crataegus orientalis] were found among the belongings of Henry Baker Tristram (1822–1906), the British cleric, ornithologist, and explorer of the Levant, in Durham, England. They later entered collections associated with the Natural History Museums in the United Kingdom.

The two anatomical models came from the research materials of the Swiss naturalist Eduard Heinrich Graeffe (1833–1916), after whom the Red Triangle Slug (Triboniophorus graeffei) is named for his collecting work in Samoa. These models later entered the archive of Slovenia's Natural History Museum in Ljubljana.

Together, the objects refer to a now-lost taxonomic note describing a rare morphological variation of Triboniophorus graeffei observed in Western Queensland, marked by a peculiar square-shaped dermal pattern.

The anomaly surfaced in correspondence between Graeffe and Tristram following their meeting at the First International Congress of Zoology in Paris in 1889. During a conversation, Tristram recounted an oral Greek Orthodox legend from Cyprus describing a hermaphroditic pagan saint whose epileptic visions foretold the emergence of a future prophet and his sign within a blood-marked veil — recalling both the Veil of Veronica and the veiled depictions of the Prophet Muhammad in Ottoman and Persian miniatures. The central image of her visions was a fluctuating red square appearing on a piece of cloth.

Shortly after, Graeffe received specimens of slugs bearing a similar square marking from his successors in Samoa. He sent several to Tristram, noting a European folk belief that certain molluscs could cure persistent warts. The cleric had reportedly suffered from the ailment since his fieldwork in Palestine, most likely contracted through intimate contact.

These objects are parafictional. They are part of a lecture performance by Hasan.
