Nestorian Stele
Cattaneo's system, with its accounting for the tones, was not lost, however. It was used e.g. by Michał Boym and his two Chinese assistants in the first publication of the original and Romanized text of the Nestorian Stele, which appeared in "China Illustrata" (1667) — an encyclopedic-scope work compiled by Athanasius Kircher.
