In the "Spiral Columns" 2020 series Zhang re-introduces the Solomonic or “spiral” columns first inserted in her works in 2017 and which appear to emerge out of colour-radiant and iridescent digital planes. Spiral columns exist in Roman and English churches, engravings, and in numerous Baroque paintings and came to Zhang’s attention when she spent one year living at the British School at Rome. The first such columns that caught her eye were the spiral columns at St. Peter’s cloister which had existed in the old basilica and are said to have been brought from Jerusalem via Greece. The recycling of material from older buildings in the East and placed in the West signals the passage of architecture and its arrangements through world cultures appearing centuries later and continents apart: like Zhang’s own belief in the insistence of forms and objects transcending time in eternal repetition.
