For Paul Lorenz, his latest line of work started with a single line.

Then another, and another one after that.

Soon his lines turned into art, yielding a series of pieces that Lorenz has made into his show “Architecture and Moment.” The show features about 30 pieces, 15 of which are the full size line art, which measure about three feet by three feet.

Each piece, Lorenz says, has an average of 1,200 lines.

“After a while, you start to see relationships between the lines,” Lorenz said. “You start to understand how they work together. Then you see shapes or patterns start. The pieces really take a life of their own.”

The idea for his work came from his time at the Illinois Institute of Technology. Because his parents didn’t allow him the option of majoring in fine art, Lorenz received a degree in engineering. It was there that he learned how lines can form something bigger and more poignant.

“There was a drafting exercise there, and you really got to understand the power of lines,” Lorenz said. “One line can turn into a cube, which can turn into a structure, which can turn into a building. It was just like my art.”

The lines on Lorenz’s work are done with graphite, so most of the pieces are completely pencil-drawn. Although some have color over the top of the design, the main focus is on the lines and their purpose. When he started the work in March, he also came up with an easier way to count the lines.

“Every tenth line, I sharpen my pencil,” Lorenz said. “Every hundredth line, I switch pencils. I always ended on a round number. It was really intense, I worked on them all so much.”

“Architecture and Moment” is being shown for the next month at Gallery 1025. Lorenz’s art is also being featured in the “Faces of Abstraction,” an exhibition which also features the work of Laura Eklund and Bob Lockhart, in Louisville at the Pyro Gallery. That show will run through Oct. 16.
