Zayya was a traveling mystic and healer who lived between the 4th and 5th centuries. Born in Palestine, he eventually journeyed to northern Mesopotamia to spread the Christian faith. During his missionary work, he was accompanied by his disciple, St. Tawor. He is recognized as a significant figure within the Assyrian Church of the East, as well as in Catholic and other pre-schism traditions.
Life and mission

After leaving his birthplace in Palestine, Zayya traveled extensively to perform healing and missionary work. He focused much of his activity in northern Mesopotamia. His ministry was conducted alongside St. Tawor, and his life spanned from 309 to 431. He is ultimately buried in the Jilu district, which is located in present-day Turkey.
Veneration and patronage

As a patron of travelers and the Jilu district, Zayya is invoked to protect against plague and famine. He is often represented in art as an equestrian saint carrying a spear. His devotion is maintained through various shrines in Syria, Iraq, and Iran, as well as through cathedrals in Australia and the United States.
Feast days
The saint is commemorated on several dates throughout the year. While his birth is observed on May 26, the Jilu feast day occurs on September 13. Additionally, his death is marked by a commemoration on the first Wednesday of January.
