Unusual to find Ganesha and Saraswati sharing the same peetha. Calendar arts from the twentieth century and modern-day silver medallions show Ganesha, Lakshmi and Saraswati together. But to find such a bronze vigraha of considerable age is a privilege.
Sarawati is identified by her attributes a veena, Akshamala, a swan and Pustaka. Clockwise starting from the lower right hand. Swan is Saraswati’s vahana and here it is shown as one of her attributes. Unusual it may be, I have one other such example in my collection.
Ganesha is holding Modaka, noose and Ankusha in his hands. Starting from his lower right hand and clockwise. The attribute in his lower left hand is not discernible. Ganesha’s vahana, a rat, is on his right. Please see the side view.
So far I have not come across any literature that would ‘explain’ Ganesha and Saraswati sharing the same peetha. Saraswati is normally associated with Bramha or Vishnu.
Lakshmi Ganapati is a documented iconography, with Lakshmi sitting on Ganesha’s lap.
The Vigraha is about 8.5 cm in height. This may be from Tamil Nadu or Andhra. Going by the wear this may not date earlier than the eighteenth century.
