Evidence accumulates showing trans-Atlantic trade/travel by Ancient Egyptians

Evidence accumulates and shows that ancient Egyptians crossed the Atlantic 3,000 years ago, maybe more.

The Ancient Egypt signature in architecture, medicine or cultural traditions can also be seen in Peru and the Canary Islands (e.g huge rocks manipulation, anti-seismic construction techniques, trepanning, mummification..). See Karim Refaey et al, 2019.

Another source of evidence comes from the chemical analysis of some of the Egyptian mummies themselves.

In 1976, Dr. Michelle Lescott from the Museum of Natural History in Paris carried out an analysis of a sample from the mummified remains of Egyptian Pharaoh Ramses the Great. Using an electron microscope, she could observe grains of tobacco clinging to the fibers of his bandages. Tobacco arrived in Europe from South America during the time of Columbus, not before.
In the early 80’, Dr Svetlana Balabanova, a forensic toxicologist at the Institute of Forensic Medicine at ULM, analysed samples of intestinal tissue from deep inside Ramses, and she discovered traces of cannabis, coca and tobacco. Later in 1992, seven ancient Egyptian mummies were transferred from the Cairo Museum to Munich for further analysis. Dr. Balabanova conducted a series of gas chromatography tests on samples of the seven mummies, one of which was of Henut Taui, a priestess of the 21st Dynasty around 1000 BC. Each sample - hence the seven individuals - contained nicotine and cocaine.

For recent research about the presence of cocaine in Egyptian mummies, see also Dominique Gorlitz, 2016.
