I am attempting to put up some of Pothana's works on this page. You shoould be able to read the contents  in Telugu using a UNICODE font. I found the  Pothana2000  font the most readable - the most delightful, actually. However, that font will only work on Win machines. Among  the versions of Windows,  XP seems to have the best  out-of-the-box  rendering  of Telugu in UNICODE.

First off,  there is  the Bhogini Dandakam - this  is a  minor  work of  Pothana, written before the Bhagavatam.
