v2.c77.245

“The churning of क्षीरार्णव by gods and demons brought forth, along with several other valuables, a charming tender-limbed divine tree सुरतरू with variegated पत्र, पुष्प and फल. The नागर style of architecture came into being in the eastern, द्राविड, in the southern, and वेसर in the nothern branches of that सुरतरू, respectively. नागर puts forth leaves in वसन्त (spring), द्राविड in ग्रीष्म (summer) and वेसर in शरद् (autumn). In a general way, नागर style is prevalent in पूर्वदेश, while द्राविड owes its origin to कर्णाटक and वेसर to the north. नागर being विप्र, is white in colour; द्राविड being क्षत्रिय, is red; while वेसर is वैश्य and green.
