"Thunderbird" recounts the story of an ancient legend of a temple commissioned by the Sumerian ruler Gudea and dedicated to the god Ningirsu and his avatar the Thunderbird. It was believed that the gods sent a divine vision to Gudea, a dream that inspired the building of the temple. In response to the destruction and pillage of the last major archaeological sites in the Middle East, Rebet animates this divine myth which was inscribed on some ancient terracotta pillars that were discovered in the region.
