Infrared imaging revealed previously unreadable characters on the wood—a standard writing surface in Japan before paper—that named a Persian official living in the country.
The official worked at an academy where government officials were trained, said Akihiro Watanabe, a researcher at the Nara National Research Institute for Cultural Properties.
The official may have been teaching mathematics, Watanabe added, pointing to ancient Iran’s expertise in the subject.
“Although earlier studies have suggested there were exchanges with Persia as early as the 7th century, this is the first time a person as far away as Persia was known to have worked in Japan (during the period),” he said.
