Chart of Southern Africa, and of the Islands of Madagascar, Bourbon and Mauritius.

Description

Before the Suez Canal Changed Everything

This is a large 1856 James Imray & Son sea chart of Southern Africa, Madagascar, and the Western Indian Ocean, compiled principally from surveys made by order of the British Government. Published at the height of British imperial expansion along the Cape Route — more than a decade before the Suez Canal would redirect global maritime traffic — it stands as a major working chart of one of the most strategically important sea lanes of the 19th century. Handsome in presentation and rich in navigational detail, it is an exceptional document of mid-Victorian hydrographic publishing.

The Map in Detail

Coverage extends to the southern tip of the African continent, including the Cape Colony coast, rendered in considerable detail, alongside the Mozambique Channel, Madagascar, and the islands of Bourbon (Réunion) and Mauritius to the east. A suite of detailed inset harbor plans occupies the upper left, including False Bay, Table Bay, Simon’s Bay, Algoa Bay, and Port Natal — the principal anchorages serving vessels rounding the Cape. Coastal elevation profiles showing the shoreline silhouette as seen from the sea are provided as landfall guides. Multiple compass roses, rhumb lines, and navigational annotations complete the chart’s practical apparatus.

Historical Context

In 1856, the Cape Route around southern Africa remained the sole practical passage between Europe and Asia, carrying an enormous volume of commercial and imperial shipping. The date places the chart at a pivotal moment in South African colonial history: the Cape Colony and Natal were consolidating under British administration, the Orange Free State had only recently been established, and the interior of the subcontinent was rapidly being mapped and contested. The inclusion of Bourbon and Mauritius reflects their continuing role as critical resupply stations on the eastern passage. James Imray & Son occupied an important niche in the London chart trade as a commercial publisher — distinct from the official Admiralty Hydrographic Office but drawing on Admiralty surveys — serving the large merchant fleet that required affordable, reliable charts outside official naval supply channels.

Publication History and Census

James Imray & Son was among the most prominent commercial chart publishers in mid-19th-century London. The firm issued and periodically updated charts across all major trade routes; this chart, dated 1856, represents one such issue of their southern African coverage.
