In the latest Age of Invention newsletter, Anton Howes reviews a book on English trade … a very old book:

I’ve become engrossed this week by a book written in 1638 by the merchant Lewes Roberts — The Marchant’s Mappe of Commerce. It is, in effect, a guide to how to be a merchant, and an extremely comprehensive one too. For every trading centre he could gather information about, Roberts noted the coins that were current, their exchange rates, and the precise weights and measures in use. He set down the various customs duties, down even to the precise bribes you’d be expected to pay to various officials. In Smyrna, for example, Roberts recommended you offer the local qadi some cloth and coney-skins for a vest, the qadi‘s servant some English-made cloth, and their janissary guard a few gold coins.

Unusually for so many books of the period, Roberts was also careful to be accurate. He often noted whether his information came from personal experience, giving the dates of his time in a place, or whether it came second-hand. When he was unsure of details, he recommended consulting with better experts. And myths — like the rumour he heard that the Prophet Muhammad’s remains at Mecca were in an iron casket suspended from the ceiling by a gigantic diamond-like magnet called an adamant — were thoroughly busted. Given his accuracy and care, it’s no wonder that the book, in various revised editions, was in print for almost sixty years after his death. (He died just three years after publication.)

What’s most interesting about it to me, however, is Roberts’s single-minded view of English commerce. The entire world is viewed through the lens of opportunities for trade, taking note of the commodities and manufactures of every region, as well as their principal ports and emporia. A place’s antiquarian or religious tourist sites, which generally make up the bulk of so many other geographical works, are given (mercifully) short shrift. Indeed, because the book was not written with an international audience in mind, it also passes over many trades with which the English were not involved, or from which they were even excluded. It thus provides a remarkably detailed snapshot of what exactly English merchants were interested in and up to on the eve of civil war; and right at the tail end of a century of unprecedented growth in London’s population, itself seemingly led by its expansion of English commerce.

So, what did English merchants consider important? It’s especially illuminating about England’s trade in the Atlantic — or rather, the lack thereof.

Roberts spends remarkably little time on the Americas, which he refers to as the continents of Mexicana (North America) and Peruana (South America). Most of his mentions of English involvement are about which privateers had once raided which Spanish-owned colonies, and he gives especial attention to the seasonal fishing for cod off the coast of Newfoundland — a major export trade to the Mediterranean, and a source of employment to many English West Country farmers, who he refers to as being like otters for spending half their lives on land and the other half on sea.

But as for the recently-established English colonies on the mainland, which Roberts refers to collectively as Virginia, he writes barely a few sentences. Although he reproduces some of the propaganda about what is to be found there — no mention yet of tobacco by the way, with the list consisting largely of foodstuffs, forest products, tar, pitch, and a few ores — the entirety of New England is summarised only as a place “said to be” resorted to by religious dissenters. The island colonies on Barbados and Bermuda were also either too small or too recently established to merit much attention. To the worldly London merchant then, the New World was still peripheral — barely an afterthought, with the two continents meriting a mere 11 pages, versus Africa’s 45, Asia’s 108, and Europe’s 262.

The reason for this was that the English were excluded from trading directly with the New World by the Spanish. It was, as Roberts jealously put it, “shut up from the eyes of all strangers”. The Spanish were not only profiting from the continent’s mines of gold and silver, but he also complained of their monopoly over the export of European manufactures to its colonies there. It’s a striking foreshadowing of what was, in the eighteenth century, to become one of the most important features of the Atlantic economy — the market that the growing colonies would one day provide for British goods. Indeed, Roberts’s most common condemnation of the Spanish was for having killed so many natives, thereby extinguishing the major market that had already been there: “had not the sword of these bloodsuckers ended so many millions of lives in so short a time, trade might have seen a larger harvest”. The genocide had, in Roberts’s view, not only been horrific, but impoverished Europe too (he was similarly upset that the Spanish had slaughtered so many of the natives of the Bahamas, known for the “matchless beauty of their women”).
