Ostrich Egg Globe

The map carved on the globe is an extremely close, if not identical, match to the Hunt–Lenox Globe, a copper globe reliably dated to about 1510. The owner of the Ostrich Egg Globe, Stefaan Missinne, claims that it was made in the early 16th century and is therefore the first globe ever to depict the New World.

The globe's primary investigator, Stefaan Missinne, claimed in 2013 that the globe had been "found" at the London Map Fair in 2012, by an owner who preferred to remain anonymous; that it had passed through at least two dealers' hands already; and that it "had been part of an important European collection for many decades" before that.^{[citation needed]}

Missinne further claimed that the remarkable similarity between the maps on the Hunt–Lenox Globe and the Ostrich Egg Globe indicated that contrary to popular belief, "the Lenox Globe was not engraved, but rather cast from the ostrich egg globe using a very specific and unusual technique," and that in fact this casting process must have happened before the two halves of the Ostrich Egg Globe were joined, giving the Ostrich Egg Globe effectively the same age as the Hunt–Lenox Globe.^{[citation needed]}

Further, in 2013, Missinne claimed that the globe showed "influence from Leonardo's workshop."^: 19 By 2017 he had gained enough certainty to claim that the globe was crafted in precisely 1504 by a left-handed engraver whom Missinne identifies as Leonardo da Vinci himself.^{[citation needed]}

In 2018, Missinne published a book titled The Da Vinci Globe (the title a reference to The Da Vinci Code (2003)) promoting his theory of the globe's provenance. Cartographer Wouter Bracke, reviewing The Da Vinci Globe in 2019, stated that Missine's book should be considered "a report on the author's research into the globe and [not] a final scientific and academic publication," and that Cambridge Scholars Publishing's lack of editorial board "clearly failed to guide the author in the preparation of his publication." Ultimately, while Bracke seems to accept the idea that the Ostrich Egg Globe is a true product of the "early 16th century," he states that more research is needed into its provenance and recent history.
