This is a pretty big find, and the connection to Baal seems likely:
A massive cult complex, dating back about 3,300 years, has been discovered at the site of Tel Burna in Israel.
While archaeologists have not fully excavated the cult complex, they can tell it was quite large, as the courtyard alone was 52 by 52 feet (16 by 16 meters). Inside the complex, researchers discovered three connected cups, fragments of facemasks, massive jars that are almost as big as a person and burnt animal bones that may indicate sacrificial rituals.
The archaeologists said they aren’t sure who was worshipped at the complex, though Baal, the Canaanite storm god, is a possibility. “The letters of Ugarit [an ancient site in modern-day Syria] suggest that of the Canaanite pantheon, Baal, the Canaanite storm god, would have been the most likely candidate,” Itzhaq Shai, a professor at Ariel University who is directing a research project at Tel Burna, told Live Science in an email.
The artifacts include fragments of two masks. “The burna mask fragments, both of noses, are quite interesting, because they are quite large, although as seen in [a photo], they were clearly meant to be worn,” Shai said.
“It is difficult to determine exactly who the masks are depicting and whether it is a specific image. In general, masks are known to have been used in cultic ceremonies and processions.”
The researchers also found massive “pithoi” vessels (large storage jars), some almost as big as a person. “Along the eastern edge of the exposed area of the building, a row of sunken pithoi, with several smaller vessels found inside of them, were found,” said Shai. Two of the vessels were imported from Cyprus, as indicated by their design.
Worship of the Baalim draws the condemnation of God in Judges, 1 Kings, and elsewhere in the Bible. Baal was a Canaanite thunder god (Hadad), but the name could also refer to various local gods.
