Joannes Actuarius

From Wikipedia, the free encyclopedia

Joannes Zacharias Actuarius (c. 1275—c. 1328^[1]) was a Byzantine physician in Constantinople. He wrote several books on medicinal subjects, particularly, an extensive treatise about the urines and uroscopy. Around 1299, he considered moving to Thessaloniki, but decided to stay in Constantinople; later, he was appointed chief physician to the Emperor.

Some of his works have been translated into Latin, and published in the 16th century.^[2]
