What happens when photography becomes a tool for social change rather than just documentation? In this episode, Michael Dooney speaks with acclaimed British photographer and artist Mark Neville about his journey from art school to the front-lines of conflict, and how he uses collaborative photography projects to empower communities, challenge social norms, and effect real-world impact. Neville shares stories from his time as an official war artist in Afghanistan, discusses the making of influential projects like The Port Glasgow Book Project and Stop Tanks With Books , and reflects on his ongoing work in Ukraine. Listeners will gain insights into the ethics of documentary practice, the power of art as activism, and what it means to make photography for—and with—the people it represents.

Mark Neville (b. 1966, London) is a British artist and photographer renowned for his socially engaged practice at the intersection of art, documentary, and activism. His projects often involve close collaboration with communities, aiming to empower subjects and address issues such as inequality, mental health, and conflict. Notable works include The Port Glasgow Book Project , Battle Against Stigma , Fancy Pictures , and Stop Tanks With Books . Neville has exhibited internationally, worked as an official war artist in Afghanistan, and was nominated for the Pulitzer Prize by The New York Times in 2012.

We turn to the astronomy of Mesoamerica, with a particular focus on the Maya and Aztec. The central feature of their astronomy was a pair of interlocking calendars which regulated all aspects of life. The surviving Maya manuscripts also deal extensively with the motion of Venus, which may also have driven decisions to go to war. We also look at the famous Aztec Sun Stone, the 2012 phenomenon, and the fall of the Itzá Kingdom. NOTE: The Song of Urania will be going on hiatus and will return on the first full moon of 2026.…

After the fall of the Mongol Yuan Dynasty, the Ming Dynasty drove the few small Nestorian Christian communities in China underground and largely closed China off to foreigners. Only in the 16th century with the arrival of Portuguese traders did contacts with the West begin to be revived. The newly founded Jesuit order organized a mission to China led by Matteo Ricci. After finding his efforts at establishing a presence in the country stymied by the government, Ricci discovered that the key to securing a permanent Jesuit presence in China was his knowledge of Western astronomy.…

After briefly examining the astronomy of Timocharis and Aristyllus, who developed the first known stellar catalog, we turn our attention to Hipparchus, who I claim was the greatest astronomer of ancient times. Hipparchus made major developments in virtually every area of astronomy known to him. His measurement of the lengths of the year and month were of unprecedented accuracy, he measured the distance to the Moon, and he developed a star catalog that was an order of magnitude larger than the earlier catalog of Timocharis and Aristyllus, which he was able to use to discover the precession of the equinoxes.…
