In 2003, Zias and Émile Puech discovered two mid-4th-century inscriptions on the 1st-century monument known as the Tomb of Absalom, which support the concept known from Byzantine period sources that a tradition existed at the time, wrongly identifying the funeral monument as the tomb of James, the brother of Jesus; Zechariah, the father of John the Baptist; and Simeon, the old priest from the Gospel of Luke.
"[4] In 2005, archaeologist Yotam Tepper was in charge of a dig near Megiddo, Israel, uncovering the ruins of what was clearly an early Christian church.
Zias, however, disagreed in print: "My gut feeling is that we are looking at a Roman building that may have been converted to a church at a later date.
[5] Years after archaeologist Yigael Yadin literally wrote the book on Masada, claiming that human remains found at the site were those of the last Jewish defenders of the stronghold, which led the Israeli government to provide them a formal state burial in 1969, Zias and forensic expert Azriel Gorski presented evidence that the remains may, in fact, have been those of Roman occupiers.
"[7] These and later comments by Zias led Jacobovici to sue for libel, winning a judgment of ₪800,000 from a Jerusalem court in 2015.
