Tracks on the Ocean: A History of Trailblazing, Maps and Maritime Travel

Rate this book
From their first appearance on Renaissance maps, linear tracks representing maritime voyages have shaped the way we see the world. But why do we depict journeys as lines, and what is their deeper meaning? Ferdinand Magellan's route to the Pacific embodied the promise of adventure and colonisation, while the scientific charts of the Royal Navy inspired others to plan conquests, navigate treacherous waters and establish settlements across the oceans.

In Tracks on the Ocean, prize-winning historian Sara Caputo charts a hidden history of the modern world through the tracks left on maps and the sea. Taking us from ancient Greek itineraries to twenty-first-century digital mapping, via the voyages of Drake and Cook, the decks of Napoleonic warships and the boiler rooms of ocean liners, Caputo reveals how marks on maps have changed the course of modernity.

In Tracks on the Ocean, Sara Caputo focuses on another imaginative leap, this one made by the anonymous sailors who, for long-forgotten reasons, decided to record their voyages as a line on their charts. In her inventive cartographic history, Caputo frames these tracks as conceptual tools as well as narrative ones. Sometimes ‘simple [and] unidirectional’, sometimes a ‘puzzling maze of pencilled lines’, they provoke discussions of celebrity, patriotism, secrecy, and surveillance.

Sometime after the voyages of Vikings and Columbus alike, the notion from the biblical Book of Wisdom that a ‘ship follows no path and leaves no signs’ was dramatically overturned. Why? Like Haywood, Caputo sees the ocean as a precipitating factor. Terrestrial journeys did not inspire their protagonists to trace out paths for the simple reason that roads already showed their progress. But in the 16th century, ‘ship tracks appear almost out of nowhere’.

Oh, how disappointing. "Trailblazing" should be an exciting subject, but Sara Caputo (an apt surname) gives us an academic thesis riddled with the usual academic obsessions with imperialism and the exercise of power.

Shit. Filled with anecdotes that have no follow up with the subject they are talking about.

Constant downgrading of Indigenous cultures feats on the ocean and the possibility they could have done their seafaring WITHOUT influence from the west! Key example Pacific Islanders, PNG, Timor, and Indigenous Australians.

Also, in the first few chapters where they talk about who invented maps and the different types of maps, again with the downgrading of Indigenous cultures. The oldest continuous culture on earth, Indigenous Australians, have been painting aerial and hydrographic maps and there is NO mention of them but a tiny reference to a South American Indigenous group but AGAIN referenced to the possibility of them being influenced by the west 😒

Cuốn này ngược lại với cuốn "DNA cổ đại" đã review trước đó, thiên về story-telling và rõ ràng là cuốn hơn hẳn. Nó sẽ khám phá các đường hải tuyến được tạo ra thế nào và bằng cách nào trong lịch sử loài người, khởi phát từ các bản đồ ghi lại chặng đường trong Kinh Thánh đến khi khoa học - địa lý phát triển, chúng dùng để khai phá các vùng đất mới, được thủy thủ dùng để đánh dấu đường đi và nhanh chóng trở thành công cụ giám sát, chuyển từ để "giám sát" sang "bị"giám sát. Sau đó, tác giả cũng bàn nhiều hơn đến các chủ đề bên lề: môi trường, giới tính lẫn chủ nghĩa giám sát. Cuốn sách được viết khá dễ chịu, đi kèm với nhiều dẫn chứng thú vị, qua đó cũng bàn về ngành bản đồ học từ cổ chí kim. Những câu punch-line khép lại các chương hoặc đoạn cũng rất thú vị. Chỉ là nó thiếu 1 sự phản tư gì đó để lại ấn tượng, bởi nhìn chung nó vẫn đi theo 2 cách riêng biệt: theo chiều lịch sử và đặt góc nhìn vào các cộng đồng bên lề.

I picked this book up on a whim whilst visiting Maritime Greenwich - and I'm so glad I did! This is a fascinating, well-written, and brilliantly researched book about maps and maritime travel. It's academic, but highly readable and engaging. It also poses some thoughtful questions about how we record the history of travel and exploration - and about the voices who are not heard. Highly recommended.

This was an interesting read, with quite a unique premise I think, investigating how and why we’re using tracks on maps to represent journeys, especially on the sea. That being said often it was a bit convoluted and also jumped between topics and points quite wildly. Every chapter opened with an anecdote but then by the end when it closed with the anecdote I often didn’ feel like it was well connected. I think I’ll remember some interesting fun facts, but that’s about it.

Fascinating description on how sailors and others plot their courses on the high seas.
