[Q]: When did Zahm die?, Context: Father Joseph Carrier, C.S.C. was Director of the Science Museum and the Library and Professor of Chemistry and Physics until 1874. Carrier taught that scientific research and its promise for progress were not antagonistic to the ideals of intellectual and moral culture endorsed by the Church. One of Carrier's students was Father John Augustine Zahm (1851–1921) who was made Professor and Co-Director of the Science Department at age 23 and by 1900 was a nationally prominent scientist and naturalist. Zahm was active in the Catholic Summer School movement, which introduced Catholic laity to contemporary intellectual issues. His book Evolution and Dogma (1896) defended certain aspects of evolutionary theory as true, and argued, moreover, that even the great Church teachers Thomas Aquinas and Augustine taught something like it. The intervention of Irish American Catholics in Rome prevented Zahm's censure by the Vatican. In 1913, Zahm and former President Theodore Roosevelt embarked on a major expedition through the Amazon.
[A]: 1921


[Q]: What was the church of San Tommaso  in Formis which has a mosaic medallion for?, Context: The last great period of Roman mosaic art was the 12th–13th century when Rome developed its own distinctive artistic style, free from the strict rules of eastern tradition and with a more realistic portrayal of figures in the space. Well-known works of this period are the floral mosaics of the Basilica di San Clemente, the façade of Santa Maria in Trastevere and San Paolo fuori le Mura. The beautiful apse mosaic of Santa Maria in Trastevere (1140) depicts Christ and Mary sitting next to each other on the heavenly throne, the first example of this iconographic scheme. A similar mosaic, the Coronation of the Virgin, decorates the apse of Santa Maria Maggiore. It is a work of Jacopo Torriti from 1295. The mosaics of Torriti and Jacopo da Camerino in the apse of San Giovanni in Laterano from 1288–94 were thoroughly restored in 1884. The apse mosaic of San Crisogono is attributed to Pietro Cavallini, the greatest Roman painter of the 13th century. Six scenes from the life of Mary in Santa Maria in Trastevere were also executed by Cavallini in 1290. These mosaics are praised for their realistic portrayal and attempts of perspective. There is an interesting mosaic medaillon from 1210 above the gate of the church of San Tommaso in Formis showing Christ enthroned between a white and a black slave. The church belonged to the Order of the Trinitarians which was devoted to ransoming Christian slaves.
[A]: ransoming Christian slaves
