Hello, This might be of interest to researchers. "Zodiac Calendars in the Dead Sea Scrolls and Their Reception - Ancient Astronomy and Astrology in Early Judaism" by Helen Jacobus is a recent scholarly book (2014) about ancient middle-eastern astronomy which also handles the subject of Greco-Roman zodiac sundials in chapter 4. The entire work seems very well documented.
