The book offers several key insights, though presented through the lens of 17th-century colonial thought:
1. **The Nature of Early Modern Travelogue:** Ogilby's work exemplifies the genre of the travelogue popular in the 17th century. These accounts mixed factual observations with geographical curiosity, commercial interest, and often, a degree of romanticism or exaggeration. Readers expected descriptions of exotic lands, potential resources, and sometimes dramatic encounters. Ogilby aimed to satisfy this demand, providing practical information for merchants and adventurers while also indulging in the wonder of discovery.
2. **Colonial Attitudes and Biases:** The book reveals the ingrained attitudes of the era towards colonialism and race. Descriptions of the Spanish colony often focus on its wealth, but also subtly or overtly reflect a sense of European superiority. The treatment of enslaved Africans is mentioned factually but rarely sympathetically, reflecting the brutal reality of chattel slavery normalized by the colonial powers. Ogilby's narrative largely supports the colonial project, presenting Spain's rule in the Caribbean as established but not necessarily benevolent.
3. **Geographical Knowledge and Exploration:** While sometimes inaccurate (a common trait of early exploration reports), the book contributes to geographical knowledge of the Lesser Antilles and Cartagena. It details the routes taken, the islands visited (like Montserrat and Dominica, which were sparsely mapped or unknown to many English readers), and provides contemporary observations that, even if flawed, offer a snapshot of the region.
4. **The Role of Publishers and Authorship:** Ogilby was primarily a publisher and mapmaker, not a traditional explorer or scientist. This highlights how travel accounts were often produced by entrepreneurs who commissioned narratives to boost interest and investment in overseas ventures. The 'expedition' described is filtered through Ogilby's writing style and purpose, which was partly commercial and promotional.
5. **Contrasting Perspectives:** Although Ogilby presents a predominantly European viewpoint, his account occasionally includes information about local customs, languages, and environments, however superficially. This provides a faint echo of the 'otherness' experienced by the travellers, even if it's quickly subsumed within the framework of European exploration and encounter.
