"Local artist Greg Harris single-handedly chiseled an artful Celtic cross out of the center of a 20-foot-high boulder. It took nearly two years," the Roadside America reports..

"This is such an awesome site in person -- so much better than it even appears in photographs. Don't miss the smaller carved cross on the back of the stone at the entrance.

"Local artist Greg Harris hollowed out a huge 20-foot-high boulder to create the cross, which took 23 months of persistent chip, chip, chipping."

"Nestled in the hills of Rocky Point, this Celtic Cross is one of the most amazing pieces of art you’ll ever see. It was conceived by Gary and Lynn Dauby, owners of Blue Heron Vineyards and Winery, and carved by Greg Harris, a local sculptor based in Cannelton," the Renew Cannelton says.

"The cross was sculpted within a single 22′ tall stone that is natural to the hillside. It is believed to be the largest known “in-situ” (of its own stone) Celtic Cross in the world. Blue Heron Vineyards and Winery is located just a short distance from downtown Cannelton."

"Greg Harris, local sculptor and Renaissance man, is the creator of a High Celtic Cross commissioned by Gary and Lynn Dauby on Blue Heron Vineyard property. The cross has been carved within a 20’x 22’ x 4’ stone that is natural to the hillside," the Blue Heron Vines says.

"Greg spent 23 months carving this piece, working 6 days a week from morning until dark, in the cold and ice of winter and the heat and humidity of summer. “I was a slave to the environment,” he once said. Where others would carve in a controlled studio with assistants to do the “dirty” work, Harris faced the elements faithfully, alone…and won.

"A number of things make this particular piece interesting. For one, we believe it to be the largest “insitu" (of its own stone) Celtic Cross in the world. Second, the number 23 is repeated time after time within the cross. There are 23 circles or arcs found in the design and 23” is the distance from the center of the circle to the center of the nodules in the upper segment. Those of you who study numbers, realize that 23 is significant. In the sports world, for instance, the number 23 is worn by our premier athletes (i.e. Michael Jordan, Lebron James and soccer star David Beckham). In the Bible, the 23rd Psalm is vital to understanding our faith in God. The entire sculpture, for that matter is built on prime numbers and is a model of the “Golden Mean” used in art and design throughout history."

"Carved within a 20’ x 22’ x 4’ sandstone boulder natural to the hillside, this artwork is believed to be the largest “in situ” (of its own stone) Celtic cross in the world," the Southern Indiana Living says.

"The cross was commissioned by Gary and Lynn Dauby, the winery’s owners, and carved by Cannelton sculptor Greg Harris, whose story is as intriguing as is the presence of this monolith in the hills of southern Indiana. Harris is completely self-taught. He began carving when he was 9 or 10, making dogwood flowers on rocks using a screwdriver.

"It took Harris 23 months to complete the Celtic cross – working alone, six days a week, through all types of weather. “Three tons of stone came out of that boulder,” Harris said. “I went through 70 power chisels.”

"The Celtic cross is a form of Christian cross featuring a nimbus or ring that emerged in Ireland, France and Great Britain in the Early Middle Ages. A type of ringed cross, it became widespread through its use in the stone high crosses erected across the islands, especially in regions evangelized by Irish missionaries, from the ninth through the 12th centuries.

"A staple of Insular art, the Celtic cross is essentially a Latin cross with a nimbus surrounding the intersection of the arms and stem. Scholars have debated its exact origins, but it is related to earlier crosses featuring rings. The form gained new popularity during the Celtic Revival of the 19th century; the name "Celtic cross" is a convention dating from that time. The shape, usually decorated with interlace and other motifs from Insular art, became popular for funerary monuments and other uses, and has remained so, spreading well beyond Ireland." (Wikipedia)
