Rangoli in Andhra Pradesh is called a Muggu.
The rangoli is made using a thick batter of rice flour.
Muggu are drawm in Andhra Pradesh during Telugu Dhanurmaasam. During this month people maintain their house very clean.
Its believed that God enters only those house that are clean, since cleanliness is considered next to Godlines.
Apart from maintaing house clean, there is a custom to sprinkle water on the front yard of the house and dream beautiful Muggu to invite God inside the house.
Also during Sankranti [Known as Harvest season], muggu is drawn from complete month infront of house by womens.
During this month womens use white rice flour for drawing muggu. They add colors, red kumkum and yellow turmeric (pasupu/manjal) to white muggu,
They belive, that white colour denotes purity and peace, red represents devotion and love and yellow stands for prosperity.
The designs are like chariot (ratham) with a cord to pull along. Around it (in the four corners)
are the sun, the crescent moon, the sugarcane branch, coiled serpent and a shaped pot with mango leaves at its mouth called the
kalasham (a symbol of wealth and health). The chariot keeps growing in size with each coming day till it occupies the entire front yard
on the first and second days of the festival (Bhogi and Sankranti). The chariot represents the Sun God - giver of light and energy to
the earth and its inhabitants. Also, the journey of the sun is from south to north (onset of Uttarayanam) according to our geography.
Since the festival that ends the month is a harvesting one the other figures make sense.
The coiled serpent represents the winter month of December to January.
The south Indian muggu follows geometrical patterns or dots, which are joined by lines that have a mathematical calculation.
So you see, our ancient women did have artistic traits combined with a sense of arithmetic, which they showed in the drawing patterns of the muggu.
