Artist Petros Vrellis combines a primitive loom and string knitting technique with an advanced computer algorithm to create Renaissance-inspired artwork. Like most renowned painters from his generation, El Greco, a Greek painter from the Spanish Renaissance, painted immensely rich and detailed landscapes and portraits. Petros Vrellis' knitted work is able to replicate the lushness of an El Greco using only string and a circular loom.
According to Vrellis' website, the work is knitted with a single piece of thread that loops around the pegs as many as 4,000 times and has a total length of up to 2 kilometers. Though the actual knitting is done by hand, the artist uses an algorithm to dictate the peg locations step by step. There are over 2 billion calculations necessary to output an image, which Petros Vrellis notes is "not much of a load for today's computers, but definitely an impossible task for the human brain."
