From the Star of Mysore Online:
Mandodari, wife of Ravan, is considered one of the most perfect women in Indian mythology. Why?
An upcoming filmstar allegedly raped his maid servant. His wife stood by him. A Police inspector allegedly molested a young sportswoman. His wife stood by him. Are these women Mandodaris of modern times? Media has tried and judged the accused. They are, for the media, Ravan — demon men who do not respect the rights of women. The court is undecided. They are probably Ravan. Or probably Ram.
Mandodari, queen of Lanka, is regarded as a Sati or a pious wife who stands by her hus-band no matter what. She is one of the five great heroines or Panchakanya of Hindu mythology, the other four being: Ahalya, Tara, Sita and Draupadi. All these women have fractured relationships with their husbands. Ahalya is abandoned by Rishi Gautama for having an extramarital affair; Tara marries her hus-band's younger brother Sugriva, after Vali is killed; Sita is abandoned by Ram following street-gossip even though she is faithful and chaste; and Draupadi has five husbands who gamble her away.
Mandodari deals stoically with the fact that her husband is a certified villain. Not much is known about her.
