Background Scholars have debated whether Himilco's expedition served official Carthaginian trade interests to monopolise the tin and lead trade, or whether it was undertaken independently. No specific benefit of the voyage for Carthage is mentioned by ancient sources, though some scholars suggest possible intentions of colonisation. According to Roller, Himilco may have been dispatched to explore the far north-western limits of Europe in response to reports from
Tartessos (and possibly Greek traders) of wealthy lands beyond the continent, which perhaps included tin sources. The Tartessians are known to have exploited the British tin trade in the 7th and 6th centuries BC. Himilco's exploration took place beyond what were then considered the limits of Europe, although Greek sailors such as the
Phocaeans and
Massalians had already reached at least
Ophiussa (modern Portugal), and possibly north-western
Brittany. Whether Himilco was aware of these earlier expeditions is uncertain due to Greek secrecy about their expeditions.
Reports According to Avienus, Himilco reached a coastal zone about four days of travel beyond the
Pillars of Heracles, which was then used by the fishermen of
Gades. The
Ora maritima gives little concrete information about his voyage, but mentions a "Sacred Island" (
Sacra Insula), inhabited by the Hierni, two days from the
Oestrymnides, and a nearby island inhabited by the Albiones. Himilco reached this Sacred Island, though the difficult journey reportedly took four months instead of two days. Such an exaggeration has often been interpreted as Carthaginian misdirection, but it may also be a vestige of the total length of Himilco's cruise, perhaps showing that he went elsewhere, such as the Atlantic islands. However, Himilco is unlikely to have reached the
Sargasso Sea, as it was sometimes mentioned in earlier scholarship, since it lies far out in the western Atlantic beyond the
Azores and well outside the range of his probable route.All three citations of Himilco's voyage in Avenius's poem stress its hazards: a windless, sluggish sea choked with seaweed that hindered ships, shallow shoals, frequent fog, vast rolling swells, and even sea monsters, together conveying the impression of a difficult and dangerous northern passage. It is probable that Himilco exaggerated the danger and difficulty to glorify his achievement, and perhaps to discourage Greek sailors from trade competition.
Reconstructed route Scholars have argued that the conditions described by the sources plausibly reflect a coastal voyage toward
Brittany, and perhaps beyond towards the
British Isles if the reported two-day distance from the Oestrymnides (presumably part of Brittany) is reliable. The "Sacred Island",
hierà nêsos (ἱερὰ νῆσος), mentioned in the
Ora maritima may correspond to the ancient Greek name for Ireland,
Iérnē (Ἰέρνη), although this remains speculative. This has led some scholars to suggest that Himilco may have been the first Mediterranean sailor to reach and record Ireland's name, which otherwise does not reappear in surviving literature until the 1st century BC. Avienus may also have drawn from Himilco's report the ethnonym
Albiones, which is related to the ancient name for Britain,
Albion. The Albiones were known to the
Tartessians, which may have led the Carthaginians to seek to investigate the region. == See also ==
