The J. Paul Getty Museum presents “Paolo Veneziano: Art & Devotion in 14th-Century Venice,” through Oct. 3, at the Getty Center in Los Angeles. For information, go online to www.getty.edu. Paolo Veneziano lived in 14th-century Venice, a time when the Bubonic Plague, the so-called “Black Death,” decimated one-third of the European population. During this dire period, the already devout Roman Catholic faithful were in a state of heightened spirituality, and found hope and solace in religion.
