A wonderful 1775 map of the Arctic regions of the Western Hemisphere by John Green or Braddock Mead. Focusing on Alaska (Bering Strait) and the Canadian Arctic, map covers from the Sea of Okhotsk (Penschinaska Guba) to Iceland and the east coast of Greenland; as well, from about 85 degrees north latitude to the southern shores of Greenland and Hudson Bay. Technically this is the northern panel of a massive three panel map of North and South America issued by Sayer and Bennett for the 1776 Thomas Jefferys American Atlas. Nonetheless, unlike many maps that were intended as a set, the present offering easily stands on its own.

The cartographer, Braddock Mead / John Green, is uncommonly forthright with his process and, through his many annotations, we can to some extant begin to understand his reasoning as he attempts to piece together a mostly unexplored land. We imagine him leaning over a desk strewn often conflicting maps prepared by his contemporaries. We imagine him drawing tables of latitudinal and longitudinal points drawn from the records of known navigators and comparing them with those of other cartographers - much as appears in the 'Comparative Table' at top center. Here, Mead offers his own latitudes and longitudes and compares them with those of Bellin, and D'Anville, thus arguing for the superiority of his own research. Throughout he references explorations and discoveries, often offering commentary and delineating the route of notable navigators including Baffin, Hudson, Vitus Bering, and others.

As much attention as Mead lavished on the Hudson Bay, his map's its most compelling cartography appears far to the west. Here Mead is attempting to reconcile the discoveries of Vitus Bering with earlier cartographic speculations and recently 'rediscovered' Japanese cartography. Here Mead draws heavily on maps published one year earlier by Jakob von Staehlin. It was Staehlin, working in 1774 from the records of Bering, Gvozdef, and Fedorov, among others archived in the repository of Royal Academy of Sciences at St. Petersburg, who first drew the Peninsula of Tchuktschi and defined an island named Alaschka. Technically, from the Russian perspective, Alaska (Alaschka¬), which was derived from the Aleut 'alaxsxaq' meant 'object toward which the action of the sea is directed,' 'great continent' or, quite basically, 'the mainland.' The notion that it might have been an island seems to extend from reports by Russian traders and military officers. Specifically, in 1768, Krenitsyn and Levashev, Russian naval officers, wrote of a large island called 'Alaxa' northeast of Unimak Island referenced by Alaskan natives as the 'Island of Alaschka.' Staehlin applied these reports to reconcile anomalies on the Japanese map acquired by the German naturalist, physician, and orientalist Engelbert Kaempfer - as Mead suggests here. This Japanese map shows an unnamed island in the vicinity of Alaska, which Staehlin expands in size and reorients to correspond to lands discovered by Gvozdef in the wake of the Bering-Chirikov expedition. The other islands, some of which are named, and some of which are not. Are derived from the reports of Captain Ivan Sindt (Sindo). Sindt sailed with Bering and later, in 1768, led his own expedition to the region. As some have suggested he seems to have greatly exaggerated both the size and quantity of the islands he encountered. Staehlin used this to fill in the blanks between the Kaempfer Japanese map and the Bering maps.

When Captain James Cook visited this region a few years later, in 1778, he had Staehlin's in hand. Based upon Staehlin's cartographer Cook surmised that he should be able to sail around 'Alaschka' thus making his way northward into the fabled Northwest Passage. He initially believed that he may have found such a passage at Cook Inlet, but did not explore further. Still, Cook we intensely disappointed by Staehlin's geography, of which he wrote,
What could induce him to publish so erroneous a Map in which many of these islands are jumbled in regular confusion without the least regard to the truth, and yet he is pleased to call it a very accurate little map? A map that the most illiterate of his illiterate Sea-faring men would have been ashamed to put his name to.
This map was drawn by Braddock Mead and prepared by Sayer and Bennett for publication by Thomas Jefferys in the 1776 edition of his iconic American Atlas.


Braddock Mead (c. 1688 - 1757), also known as John Green, was an Irish cartographer and map engraver active in London during the middle part of the 18th century. Mead is one of the most interesting and colorful figures in cartography who's left handed personal life sharply contrasted with the high standard of his maps. Mead was born in Ireland around 1688 and seems to have come from a good family and received a respectable education. His brother Thomas Mead held the position of Lord Mayor of Dublin in 1757. Braddock Mead left Dublin for London around 1717 where seems to have been draw to vice, subsidizing his cartographic work with various "hack jobs" and gambling. In 1728 Mead fell in with a plot to defraud a 12 year old Irish heiress, Bridget Reading, of her fortune by kidnapping and marrying her himself. Mead suffered jail time for the crime but was more fortunate than his partner, a fellow Irishman named Kimberly, who was hanged. As a cartographer Mead cannot have exhibited a more antithetical character. He held himself and others to the highest standards of accuracy and scholarship, and issued a call for greater transparency in the field of mapmaking. Mead worked with Ephraim Chambers on the Universal Dictionary, as well as with Cave and Astley in the publication of various travelogues and explorer's journals. Eventually he came to work for the publishing house of Thomas Jefferys, who saw through Mead's personal failings to appreciate his cartographic brilliance. Mead has been called the genius behind Jefferys and he seems to have had a hand in the production of many of Jefferys' most important maps. William Cumming notes that Mead

had a number of marked characteristics as a cartographer...One was his ability to collect, to analyze the value of, and to use a wide variety of sources; these he acknowledged scrupulously on the maps he designed and even more fully in accompanying remarks. Another outstanding characteristic was his intelligent compilation and careful evaluation of reports on latitudes and longitudes used in the construction of his maps, which he also entered in tables on the face of the maps...Mead's contributions to cartography stand out...At a time when the quality and the ethics of map production were at a low ebb in England, he vigorously urged and practiced the highest standards; in the making of maps and navigational charts he was in advance of his time. For this he deserves due credit.

Robert Sayer (1725 - 1794) and John Bennett (fl. 1770-1784) were an important English map and print publishing duo of the mid to late 18th century. In 1747 Sayer acquired the firm of Philip Overton from his sister-in-law, Mary Overton. From his London office on 55 Fleet St., Sayer began republishing the Overton map stock while acquiring and expanding the business with plates from other printers - including maps, portraits, and nautical engravings. Sayer partnered with Bennett sometime in the late 1760s. They published numerous works by various cartographers including Kitchen, Jefferys, Belling, d'Anville, among others. Upon Sayer's death, after nearly 50 years in the map trade, the firm was acquired by Laurie and Whittle, who would continue to republish revised and updated editions of his work for many years to come.

Thomas Jefferys (1695 - 1771) was one of the most prominent and prolific map publishers and engravers of his day. Our first records of Jefferys appear in the 1735 when he was apprenticed to Emmual Bowen. Later, in the 1740s he engraved several maps for the popular periodical The Gentlemans' Magazine. Around 1740 Jefferys was finally able to go into business for himself and in 1746 received an appointment as "Geographer to Fredrick, Prince of Wales", which shortly after translated to the position of "Royal Cartographer to King George III". While not specifically a cartographer, Jefferys specialized in compiling and re-engraving the works of earlier cartographers into coherent cartographic wholes. While not salaried position, Jefferys appointment as "Royal Cartographer" allowed him preferential access to the most up to date cartographic material available. He his best known for his maps of the America, particularly The American Atlas, which included some of the finest and most important late colonial ear maps of America ever published. Despite his prolific publishing history, royal appointments, and international publishing fame, Jefferys lived most of his life in dire economic straits. It is recorded that he had to be bailed out of bankruptcy by the Sayer firm during the publication of The American Atlas. In the end Jefferys died with very little. Nonetheless, his cartographic legacy survived him, even after his death in 1771, many of his important maps continued to be published and republished by Sayer and Bennet, Lotter, La Rouge, and others. Many attribute some of Jefferys best maps to the colorful and criminally inclined cartographic genius Braddock Mead, who is considered the "secret behind Jefferys". Jefferys was succeeded by his son, also Thomas, who had little success as a cartographer and eventually sold his stock to William Faden.
