The aesthetic activity largely revolves around ‘cognition’, and the ‘law of beauty’. It is a continuous process of human activity, which formulates, confirms and perfects the results of cognition according to the laws of beauty. Perception of an object evokes feeling. Feeling could be instant and the reaction could be subject to the condition at that time. However, such reaction is largely influenced by previous experience and matured intellect of the person. Every society reflects the views of their aesthetic values and appreciation based on their material and cultural evaluation. Medieval Period Architecture (plate 1A) in India produced some of the finest medium scale architectures. Compare to classical period (4th C AD- 8th C AD) medieval produced relatively smaller scale architecture structure. However, qualitatively they maintained the same elegance and maturity. In contrast to the earlier Classical Period Art and Architecture (India), the Medieval Period witnessed stronger appearance of decorative motifs (plate 1A). The structural elements are covered with decorative elements. In 19th Century architecture (plate 1B) the decorative quality has become lesser compare to the 16th C Baroque quality art and architecture. 20th C certainly (plate 1C) has emerged with new aesthetics concept with much clearer shape and form. Earlier decorative motifs are being minimized and the structural forms are clearly visible. The new minimalist approach has influenced in every sphere of human life- house, bridge, furniture, household consumer goods, clothing, place of worship, public structures. The modern architectural vernacular revolves around simplicity in form. A new aesthetic appears that was not known to earlier era.
