Yes, according to traditional Jain cosmology, the earth (referred to as "Jambudvipa") is described as being flat and circular in shape. Jain scriptures, such as the Tattvartha Sutra and various cosmological texts like the Tiloyapannatti and Trilokasara, present a detailed model of the universe where the central continent, Jambudvipa, is a flat disc surrounded by concentric rings of land and ocean. This cosmological view is symbolic and forms an important part of Jain philosophical and religious literature. However, it is important to note that this representation is based on ancient Jain scripture and is not in agreement with modern scientific understanding of the earth's shape.
