and Puranic scenes executed with detail. Above this are two friezes of yalis or makaras (imaginary beasts) and hamsas (swans). The vimana (tower) is divided into three horizontal sections and is even more ornate than the walls. Sculpture In Hoysala art Hardy identifies two conspicuous departures from the more austere Western (Later) Chalukya art:ornamental elaboration and a profusion of iconography with figure sculptures, both of which are found in abundance even on the superstructure over the shrine. Their medium, the soft chlorite schist (Soapstone) enabled a virtuoso carving style. Hoysala artists are noted for their attention to sculptural detail be it in the depiction of themes from the Hindu epics and deities or in their use of motifs such as yali, kirtimukha (gargoyles), aedicula (miniature decorative towers) on pilaster, makara (aquatic monster), birds (hamsa), spiral foliage, animals such as lions, elephants and horses, and even general aspects of daily life such as hair styles in vogue. Salabhanjika, a common form of Hoysala sculpture, is an old Indian tradition going back to Buddhist sculpture. Sala is the sala tree and is the chaste maiden. In the Hoysala idiom, madanika figures are decorative objects put at an angle on the outer walls of the temple near the roof so that worshipers circumambulating the temple can view them. The are pillar images that show traces of Chola art in the Chalukyan touches. Some of the artists working for the Hoysalas may have been from Chola country, a result of the expansion of the empire into Tamil-speaking regions of Southern India. The image of mohini on one of the pillars in the mantapa (closed hall) of the Chennakeshava temple is an example of Chola art. General life themes are portrayed on wall panels such as the way horses were reined, the type of stirrup used, the depiction of dancers, musicians, instrumentalists, and rows of animals such as lions and elephants (where no two animals are identical). Perhaps no other temple in the country depicts the Ramayana and Mahabharata epics more effectively than the Hoysaleshwara temple at Halebidu. Erotica was a subject the Hoysala artist handled with discretion. There is no exhibitionism in this, and erotic themes were carved into recesses and niches, generally miniature in form, making them inconspicuous. These erotic representations are associated with the Shakta practice. Apart from these sculptures, entire sequences from the Hindu epics (commonly the Ramayana and the Mahabharata)
