A key insight from this study reveals that the 'Feast of the Liberation of Jerusalem,' celebrated annually on 15 July, was not only a commemoration of the First Crusade's capture of Jerusalem in 1099 but also a deliberate ritual reconstruction of biblical history. The feast, established within years of 1099, involved processions that mirrored the actions of the First Crusaders while aligning Latin Jerusalem with significant Old and New Testament sites. This alignment was intended to frame the Crusade as a continuation of biblical narrative, providing a unique lens through which the inhabitants of twelfth-century Jerusalem interpreted their historical moment. The study analyzes liturgical programs and ritual processes to uncover this interpretive framework.

Archaeological evidence reveals that the Aztec ritual of 'Binding of the Years,' involving the burial of a symbolic bundle and the ceremony of 'New Fire,' traces its origins to the early Classic period of Teotihuacan. Iconographic representations, such as twisted cords and knots, correspond to stone sculptures resembling bundles of firewood, symbolizing a 52-year cycle. While the exact duration of these cycles remains uncertain, the study suggests that the practice was initially a priestly affair before becoming a broader societal event during the late Classic period. The earliest depiction of 'New Fire' in central Mexico is found at Xochicalco, post-dating Teotihuacan's decline, while a Teotihuacan-style frieze from Veracruz may depict the distribution following such ceremonies.

Harald Ingholt's previously overlooked excavation diaries from Palmyra (1924–1928) have revealed new insights into the city's funerary art and sculpture contexts. These diaries, held at the Ny Carlsberg Glyptotek, document unpublished finds—including sculptures and inscriptions—that were not included in his 1928 book or subsequent publications in <em>Berytus</em>. By cross-referencing these records with his extensive archive of Palmyrene funerary portraits (photographs, datings, and bibliographic notes), researchers have identified additional tombs and reconstructed original contexts for key artifacts. This work complements Ingholt's foundational studies on Palmyra's art, offering a deeper understanding of its chronological development and cultural significance.
