THE KASSITEROS PROJECT

The Kassiteros Project

Ancient Texts

Biblioteca Medicea Laurenziana, Plut. 70.3, fols. 133v–134r — the Cassiterides passage in Herodotus. Teca Digitale record. Digital image rights remain with the repository and are not included in the Kassiteros CC BY 4.0 licence.

This anthology brings together literary, geographical, epigraphic and documentary witnesses relevant to the Kassiteros Project’s study of metallurgy through archaeology and ancient literature.

Sources are arranged chronologically so that changing knowledge of metals, Britain and the western world can be read as a historical sequence. Ancient geography is treated as evidence in its own right: it is often the only way to judge whether silence about tin is meaningful or simply outside an author’s geographical horizon or literary purpose.

A medieval Hebrew manuscript page from the Book of Ezekiel with Latin annotations. 6th century BC (traditional setting 593–571 BC; textual formation debated)

Book of Ezekiel — Ezekiel 27

The anthology uses Ezekiel 27 as an eastern Mediterranean control on the geography of the metals trade. Its catalogue places tin among the commodities reaching Tyre and is therefore important for asking what a Near Eastern source does—and does not—say about the western termini of that trade.

Read source → An antiquarian drawing of an ancient Greek stone inscription. c. 550–500 BC onward (composite evidence series)

Epigraphic evidence for κασσίτερος and related terms

The epigraphic dossier provides a control against literary geography: metal words occur in inventories, dedications and economic documents in contexts where the object, quantity or transaction may be more tightly constrained than in narrative prose. The anthology’s SEG examples therefore help distinguish the history of a word from later stories about where the metal came from.

Read source → Roman bust of Herodotus in Athens. c. 430 BC

Herodotus — Histories

Herodotus is the earliest surviving author in the anthology to name the Cassiterides in connection with tin. More important than the name is his explicit statement that he cannot verify the far western geography: the passage preserves both a tin tradition and a contemporary limit of knowledge.

Read source → Bust of Aristotle against a dark background. Hellenistic period; date uncertain

Pseudo-Aristotle — De Mirabilibus Auscultationibus

The anthology highlights the remarkable expression “Celtic tin” and the metallurgical observations attributed to the pseudo-Aristotelian collection. These passages matter because they sit closer to technical and paradoxographical traditions than the better-known narratives of Atlantic exploration.

Read source → Bust representing Polybius. 2nd century BC; passage c. 150s BC

Polybius — Histories

Polybius is unusually valuable because he names the British Isles and “the method of obtaining tin” as a subject on which writers disagreed, then postpones the topic to a specialist geographical treatment that does not survive. The anthology uses this as evidence both for the existence of a developed discourse about British tin and for the limits of the surviving corpus.

Read source → A historical reconstruction map of the world as described by Strabo. c. 120s BC

The Nikomedes Periodos

The Periodos places Tartessos within an Atlantic–Mediterranean coastal sequence and describes tin, gold and copper arriving there from Keltike. In the anthology this is a key witness to the way a late Hellenistic geographical text connected metals, Celtic space and an Iberian emporium.

Read source → Marble portrait bust of Julius Caesar. c. 54 BC

Julius Caesar — Commentarii de Bello Gallico

Caesar supplies an independent conquest-period description of Britain, its resources, inhabitants and cross-Channel connections. The anthology is especially interested in the disputed phrase plumbum album in the interior and in the Veneti narrative, which demonstrates established maritime links between Gaul and Britain.

Read source → Historical black-and-white reproduction of a Roman bust of Cicero. 54 BC

Cicero — Epistulae ad Atticum

Cicero’s private letters are a contemporary control on Caesar’s British expedition. Their sceptical comments about British booty and precious metals illuminate what educated Romans thought might be gained from the island while events were still unfolding.

Read source → Illuminated manuscript opening of Diodorus Siculus in Latin translation. c. 49 BC

Diodorus Siculus — Bibliotheca Historica

Diodorus preserves the fullest surviving narrative of the British tin trade: extraction in Belerion, transport to a tidal island called Ictis and onward movement through Gaul. For Kassiteros it is a central text precisely because its apparently concrete geography must be tested against archaeology, geomorphology and the transmission of earlier writers.

Read source → A historical reconstruction map of the world as described by Strabo. late 1st century BC–early 1st century AD

Strabo — Geographica

Strabo is the anthology’s most important source-critical geographer. He transmits competing traditions about Britain, the Cassiterides, Atlantic navigation and the western emporia while repeatedly judging the reliability of Pytheas, Polybius and other predecessors.

Read source → A historical reconstruction map of the world as described by Strabo. c. 2 BC–early 1st century AD

Pompeius Trogus / Justin — Histories, Book 44

Trogus, surviving largely through Justin’s epitome, provides an Iberian comparator: western mineral wealth, peoples and geography are described without folding Britain into the same account. The anthology uses the author’s Narbonensian background and the overland Rhône–Narbonne context to ask what information might have circulated along western trade routes.

Read source → Historical reconstruction of Pomponius Mela’s world map. c. AD 43

Pomponius Mela — De situ orbis

Mela is valuable as a compact Roman chorography in which the Cassiterides remain tied to the Atlantic façade of Iberia while Britain receives its own island geography. The anthology uses that spatial separation to test later attempts to identify all tin-island traditions with Britain.

Read source → Historical portrait of Pliny the Elder. AD 77

Pliny the Elder — Naturalis Historia

Pliny is a junction point for geography, mineralogy and source transmission. The anthology brings together his notices of Mictim/Mictis, Vectis, Atlantic islands and the metallurgy of tin, making it possible to test whether later identifications conflate names that Pliny himself kept distinct.

Read source → Historical portrait of Tacitus. c. AD 98

Tacitus — Agricola

Tacitus describes Britain as metalliferous and discusses its geography, climate and conquest, yet does not single out tin. The anthology uses this as a post-conquest comparison with earlier tin narratives.

Read source → Medieval manuscript page of Suetonius. AD 121

Suetonius — De vita Caesarum

Suetonius provides imperial-biographical context for Caesar, Claudius, Vespasian and the Roman incorporation of Britain, including Vectis/Wight traditions in the wider conquest narrative. The anthology uses these notices to anchor political chronology around the geographical sources.

Read source → A fifteenth-century Ptolemaic world map with Europe, Africa and Asia. mid-2nd century AD

Ptolemy — Geographike Hyphegesis

Ptolemy supplies the most explicit surviving coordinate framework for Britain and its neighbouring islands. In Kassiteros this is not merely background mapping: it is a control for testing whether proposed identifications such as Ictis = Vectis or Cassiterides = Scilly are compatible with the ancient geographical tradition.

Read source → Manuscript page of Solinus. 3rd century AD (traditional dating varies)

Gaius Julius Solinus — De mirabilibus mundi

Solinus shows how earlier Roman geographical and mineral traditions were compressed into a late-antique handbook. His Britain and Hispania chapters are useful for tracing which features of Pliny and earlier writers were repeated, altered or omitted.

Read source → Portrait representing Cassius Dio. early 3rd century AD

Cassius Dio — Historia Romana

Cassius Dio returns to Caesar’s invasion and the later Roman conquest from a much later imperial perspective. The anthology uses his repeated emphasis on Britain’s remoteness and imperfect earlier knowledge as a check on retrospective certainty.

Read source → The inscribed standing stone known as Mên Scryfa in Cornwall. AD 238 onward (composite evidence series)

Inscribed stones of Cornwall and the South-West

The inscribed-stone dossier connects literary geography to archaeology by placing named, datable texts in the physical landscape of Cornwall and western Britain. Roman milestones and post-Roman memorial inscriptions demonstrate literacy, movement, authority and named communities without requiring a literary intermediary.

Read source → A historical reconstruction map of the world as described by Strabo. c. AD 240

Herodian — History of the Empire

Herodian’s account of Severus in Britain supplies a vivid late Roman topographical tradition of marshes, tides and difficult terrain. The anthology uses this to keep physical geography and travel conditions in view when assessing earlier maritime and trading narratives.

Read source → Icon of Saint Cyprian of Carthage. c. AD 252

Cyprian of Carthage — Ad Demetrianum

Cyprian’s image of exhausted gold, silver and stone deposits is included as evidence for how mining and resource depletion could function in late Roman argument. It broadens the anthology beyond tin and Britain into the social vocabulary of extraction.

Read source → Manuscript folio of the Antonine Itinerary. 3rd century AD

Antonine Itinerary — Maritime Itinerary

The Antonine Itinerary provides route-based rather than descriptive geography. Its maritime material, island names and coastal sequence are useful controls for Vectis, Silia/Scilly and the practical geography of Roman movement around Britain.

Read source → A historical reconstruction map of the world as described by Strabo. late 4th century AD

Rufius Festus Avienus — Ora Maritima

Avienus preserves an Atlantic poetic geography of Oestrymnides, Tartessos and western seaways that has often been mined for supposedly archaic information about the tin trade. The anthology includes it to trace the long afterlife of Atlantic metal geography.

Read source → A fifteenth-century Ptolemaic world map with Europe, Africa and Asia. 4th–5th century AD

Marcian of Heraclea — Periplos of the Outer Sea

Marcian reformulates Ptolemaic geography into a periplus tradition. The anthology uses his lists of coasts, peoples, islands and places to follow the transmission of Britain’s spatial vocabulary after Ptolemy.

Read source → A ninth-century manuscript page of Isidore of Seville’s Etymologiae. c. AD 403

Sulpicius Severus — Chronica

Sulpicius’ notice of exile to the Scillies is a rare late Roman literary anchor for the islands as inhabited and politically usable space. In the anthology it acts as a reality check on reconstructions that require the archipelago to have had an otherwise unattested industrial or metropolitan role.

Read source → A long, compressed Roman route map showing roads, cities and regions. late-antique route-map tradition; extant medieval copy

Peutinger Table

The Peutinger Table is included as a cartographic control on Roman route knowledge. It is especially useful for reminding the reader that surviving maps privilege connected routes and settlements rather than every economically important place.

Read source → A ninth-century manuscript page of Isidore of Seville’s Etymologiae. 5th–6th century AD

Gildas — De Excidio Britanniae

Gildas is a major narrative witness to post-Roman Britain. For Kassiteros his value lies in the political and geographical world within which later western British communities operated, rather than in direct testimony about tin.

Read source → Greek manuscript pages of Herodotus with dense handwritten marginal notes. 6th century AD

Stephanus of Byzantium — Ethnica

Stephanus is a source-transmission archive in miniature: his lexical entries preserve otherwise lost geographical notices about Kassitera, Tartessos and Brettia. The anthology uses them to trace how older metal and Atlantic traditions survived into Byzantine scholarship.

Read source → Greek manuscript pages of Herodotus with dense handwritten marginal notes. c. AD 580–640

Stephanos of Alexandria — metallurgical/alchemical text

The anthology draws attention to the expression “the British metal” within the Greek alchemical tradition. This matters to Kassiteros because it shows that Britain could function as a metallurgical geographical label far beyond the classical ethnographic texts.

Read source → A ninth-century manuscript page of Isidore of Seville’s Etymologiae. probably 7th century; traditions concern the 5th–6th centuries

Vita Sancti Samsonis

The Life of Samson gives an unusually localised narrative of movement through Cornwall and the western British world. The anthology uses its roads, settlements and social encounters as a control on what kinds of economic activity are visible in a genre not written to document metallurgy.

Read source → A ninth-century manuscript page of Isidore of Seville’s Etymologiae. c. AD 615–630

Isidore of Seville — Etymologiae

Isidore’s encyclopedia preserves late-antique geographical and metallurgical definitions, including islands, metals and tin. It is useful for tracing what a learned western reader of the early seventh century could inherit from Pliny, Solinus and related traditions.

Read source → Byzantine manuscript image of Saint John the Merciful. after AD 641

Life of St John the Almsgiver — British tin episode

The Life of St John the Almsgiver contains the striking story of a merchant who sails to Britain and exchanges cargo for tin. For Kassiteros it documents a seventh-century eastern Mediterranean literary association between Britain and tin, long after the classical Ictis tradition.

Read source → Title page of The Irish Liber Hymnorum. attributed 7th century; manuscript transmission later

Broccán’s Hymn

Broccán’s Hymn is included for the insular sea-name Muir Icht. Together with other Irish texts it helps the anthology test whether a name resembling Ictis/Vectis persisted in medieval geographical vocabulary.

Read source → A ninth-century manuscript page of Isidore of Seville’s Etymologiae. late 7th century AD

Aldhelm — Carmen Rhythmicum and Letter to Geraint

Aldhelm is important to the anthology because he writes from a world in which travel and communication between Wessex and Dumnonia were demonstrably possible. His journey through Devon and Cornwall makes the far South-West part of an informed learned landscape before Bede.

Read source → Anglo-Saxon charter of Æthelbald. c. AD 716

Æthelbald of Mercia — Worcester salt-works charter

The Worcester salt-works charter broadens the anthology’s industrial comparison beyond metal. It shows early medieval extraction and production embedded in documentary rights, property and revenue, offering a useful contrast with how poorly any comparable Cornish tin industry is documented in surviving charters of the same broad period.

Read source → Early manuscript page of Bede’s Historia Ecclesiastica. AD 731

Bede — Historia Ecclesiastica Gentis Anglorum

Bede is one of the anthology’s strongest tests of “absence of evidence” because Book 1 explicitly enumerates Britain’s natural resources, including several metals, yet does not name tin. His detailed geography and his knowledge of Wight make the omission more interesting than silence in a battle narrative or saint’s life.

Read source → Manuscript opening of the Ravenna Cosmography British section. 8th century AD

Ravenna Cosmography

The Ravenna Cosmography offers the anthology’s fullest post-Roman inventory of British place names without Ptolemy’s coordinate frame. Its South-West sequence and continuity of names such as Vectis are important for testing the persistence and transformation of ancient geography.

Read source → An illuminated page from the medieval Book of Kells. AD 825

Dicuil — De Mensura Orbis Terrae

Dicuil is a witness to the medieval survival and recombination of classical geographical authorities. The anthology is interested in his use of Pliny and Pythean material, including island distances and the transmission of names associated with the far north-western ocean.

Read source → An illuminated page from the medieval Book of Kells. c. AD 829

Historia Brittonum (attributed to Nennius)

The Historia Brittonum combines historical, geographical and marvel traditions. The anthology uses its Wight material and its explicitly metalliferous Irish lake wonder to compare where medieval writers do and do not choose to name metals.

Read source → An illuminated page from the medieval Book of Kells. 9th century AD

Cath Cathardha — Muir Icht passage

The Irish adaptation of the Roman civil-war tradition supplies another occurrence of mara/muir Icht in a channel-crossing context. The anthology uses it with Cormac and Broccán to test whether a “Sea of Wight” name was a living medieval geographical term.

Read source → Title page of Cormac’s Glossary. c. AD 900

Cormac’s Glossary (Sanas Cormaic)

Cormac’s Glossary is a lexicographical witness to medieval Irish geographical vocabulary, including forms connected in the anthology with Muir Icht and Britain/Cornwall. It is therefore part of the project’s attempt to track names across language communities rather than only across Greek and Latin texts.

Read source → Title page of the Saltair na Rann. Middle Irish; date uncertain, probably later than the 9th-century material

Saegul Adaim — “Sea of Icht”

Saegul Adaim contributes a further Middle Irish occurrence of muir n-Iucht within a synchronising historical poem. The anthology uses the recurrence to build a cumulative case that Icht/Iucht functioned as a real medieval sea-name rather than an isolated scribal curiosity.
