has kept his name fairly obscure, he ''occupies an important place in the history of Italian painting,'' according to the site.
''He was one of the earliest to depict (human) figures with a solid, three-dimensional form,'' said Karen Gould, a former University of Texas art history professor who is now an independent scholar of medieval art in Austin. ''From that point on, up until the 20th century, the human figure was one of the dominant themes of Western art. Basically, what (Cavallini) did was in the vanguard of what would dominate Western art for centuries.''
Willene Clark, an emeritus art history professor at Malboro College in Vermont, said Cavallini was a predecessor to Giotto, a better known artist who also was a first in three-dimensional painting.
''Cavallini's painting was very soft, an early humanist sort of style,'' she said. ''His figures have a lot of presence. There is a softness in the lines. ... There's a great deal of interaction with the figures. He's a wonderful painter.''
A release from the exhibit office here in Lubbock indicates that three of the paintings in the exhibit are of St. Cecilia, who is considered the patron saint of church music.
According to several Internet accounts of the legend of Cecilia, she was martyred in the fourth century for helping bury the remains of Christians who were killed for their beliefs. Legend has it that she was condemned to be suffocated in the steam of her own bathroom, but survived. She was later to be beheaded but lived for three days after the fatal blow.
''There was a whole circle of girl martyrs. She was the hometown hero of Rome,'' Lucas said. ''The cult of St. Cecilia is very old in Rome. It was an important church in the city, where pilgrimages would go.''
Before her death, she gave her home to be used as church, a common practice during times of Christian persecution in Rome, Neyland said. Through the years, the church was rebuilt several times on the original location with columns and other additions added in later years, he said.
''What happens is that you have different levels of churches in Trastevere,'' Howe said. ''When Christians built churches during the persecutions, they didn't want steeples. They wanted regular houses.''
In addition to the images of St. Cecilia in the exhibit, there also will be 11 frescoes that represent the wedding of the Virgin Mary to St. Joseph.
Such an image ''is not tremendously rare, but rare enough,'' Lucas said. ''There was a real interest in the medieval period in filling in the gaps left by the gospels. The gospel says very little about Mary and even less about Joseph. To have him in those images is significant.''
The use of sacred art by Cavallini and others to tell the story of Christianity was considered ''the Bible of the illiterate,'' Gould said.
''There were no newspapers, no printing presses,'' Neyland said. ''How did you communicate what needed to be told? You painted it. ... In Christendom, no one knew how to read or write, so the painting tells the story. The history of who we are today is based on this mode of communication.''
The exhibit, titled ''Traditions and Renewal,'' will be on display from June 2002 to August 2002 and will also include other art from the Vatican Museums as well as sacred art from the same time period in the Americas.
