The kolam, or "rangoli" is a traditional mandala, a geometric pattern, that women design in front of their houses during festivities. In Tamil culture is a strong form of expression by the women, who express their feelings in this secret way.
In Greek mythology, Bolbe (Greek: Βόλβη) was an extremely beautiful Lake Goddess or Nymph who dwelled in a Thessalian lake of the same name (modern Lake Volvi). She was the daughter of Oceanus and Tethys. Like other lake Gods and Goddesses, Bolbe's offspring were Limnades who are Nymphs living in fresh water lakes. According to Athenaeus, Bolbe was the mother of Olynthus by Heracles.
