The article examines Chilean muralism, looking at its role in articulating political struggles in urban public space through a visual political culture perspective that emphasizes its sociological and ideological context. The analysis characterizes the main themes and functions of left-wing brigade muralism and outlines four subpolitical phases: (i) Chilean mural painting’s beginnings in 1940–1950, especially following the influence of Mexican muralism, (ii) the development of brigade muralism for political persuasion under the context of revolutionary sociopolitical upheaval during the 1960s and in the socialist government of Allende from 1970 to 1973, (iii) the characteristics of muralism during the Pinochet dictatorship in the 1980s as a form of popular protest, and (iv) muralism to express broader social discontent during the return to democracy in the 1990s. How did the progressive popular culture movement represent, through murals, the political hopes during Allende’s government and then the political violence suffered under the military dictatorship? Several online repositories of photographs of left-wing brigade murals provide data for the analysis, which suggests that brigade muralism used murals mostly for political expression and for popular education. Visual art’s inherent political dimension is enmeshed in a field of power constituted by hegemony and confrontation. The muralist brigades executed murals to express their political views and offer them to all spectators because the street wall was within everyone's reach. These murals also suggested ideas that went beyond pictorial representation; thus, muralism was a process of education that invited the audience to decipher its polysemic elements.

The California missions, whose original church spaces and visual programs were produced by Iberian, Mexican, and Native artisans between 1769 and 1823, occupy an ambiguous chronological, geographical, and political space. They occupy lands that have pertained to conflicting territorialities: from Native nations, to New Spain, to Mexico, to the modern multicultural California. The physical and visual landscapes of the missions have been sites of complex and often incongruous religious experiences; historical trauma and romantic vision; Indigenous genocide, exploitation, resistance, and survivance; state building and global enterprise. This Dialogues section brings together critical voices, including especially the voices of California Indian scholars, to interrogate received models for thinking about the art historical legacies of the California missions. Together, the contributing authors move beyond and across borders and promote new decolonial strategies that strive to be responsive to the experience of California Indian communities and nations. This conversation emerges from cross-disciplinary relationships established at a two-day conference, “‘American’ Art and the Legacy of Conquest: Art at California’s Missions in the Global 18th–20th Centuries,” sponsored by the Terra Foundation for American Art and held at the University of California, Los Angeles, in November 2019.

Analysis of the iconography in a directional almanac on Codex Borgia pages 49–52 invites comparison with almanacs in a related set of divinatory manuscripts known as the Borgia Group, but one aspect of the Codex Borgia almanac remains unique. It records real-time dates employing the central Mexican system of year dates that help identify the images as year-end rituals. These fifteenth-century dates correlate with the last twenty-day “month” in the year, known as Izcalli in the Valley of Mexico and neighboring Tlaxcala. Izcalli rituals in February involved drilling a new fire, the erection of sacred trees, and animal sacrifice, all of which appear on Borgia 49–52. During Izcalli, human sacrifice was performed only every fourth year, a pattern like that seen in the Codex Borgia and the Codex Cospi, where death imagery and decapitated humans appear prominently on the fourth year-bearer page, associated with the southern direction. Borgia Group codices also depict trees and birds representing the four cardinal directions. These are most prominent on Codex Fejérváry-Mayer page 1 in a cosmogram representing two different calendar formats, like those seen in the Borgia almanac. The 5 × 52-day format was used to measure the solar year and Venus cycle, and a second set of day signs appears in a 4 × 65-day pattern useful in calculating the fifty-two-year cycle and the Venus cycle. This provides a subtext for understanding the dates represented on Borgia 49–52 and the extension of the almanac on page 53, where the Venus almanac begins.
