The Bhagavata purana(9^th Skanda) has preserved many interesting facts on ancient Ajodhya, like Pali texts. Esdras A and Esdras B of Old Testament refers to Saudasa and Sudasa of Indian puranic tradition where names of both the father and son have been included in the list of kings of Ajodhya along with Dasaratha and Khatvanga.

Name of kings of Ajodhya describes the whole of the ‘inhabited world’ and gives a complete geographical picture of it.

If we look at the description of Nimi clan of this purana, names of kings like Maharoma, Subarnaroma, and Harsharoma are seen. This purana again gives a list of names of kings under Chedi and Bidarbha dynasty where name of Romapada is seen who was the third son of Bidarbha after Krusha and Kratha.

According to Bhagavata, there were eight small islands(upadvipa) in Jambudvipa : Ramanaka, Abartaka, Svarnaprasu, Mandaharita, Panchajanya, Chandrasukala and Lanka. Name of both Lanka and Ramanaka is seen in the peripheral map of Ptolemy. In an egg-shaped or oval-shaped landmass like Jambudvipa, these two islands wer neighbourly to each other in south-west direction.

Bhavishya purana mentions name of Sage Romancha along with eight other sages like Agasti, Pulastya, Bhrugu, Usana, Gargaba, Narada  and Gomanta. These nine sages wrote nine different treaties; Romancha’s expertise was in trade, the purana says.

Writing for the ‘Introduction’ to ‘Sidhanta–darpana’,  Jogesh Chandra Ray says of Romaka Sidhanta(p.xxiv) whose Indian origin he has stressed along with Paulisha Sidhanta. This Romaka Sidhanta, perhaps, is lost now.

The name ‘Rome’ whose etymology refers to Rama of Dasaratha and Ajodhya bears its geographical testimony for whole of the ‘inhabited world’.
