Globally, the sign for Venus is used to symbolize the female principle. The name comes from the mythical Roman goddess of beauty and fertility. Never more than two signs away from the sun-sign, Venus' ruler-ship is shared by earth-sign Taurus ( April 21-May 21) and air-sign Libra (September 23-October 23). Here beauty and attraction, harmony, a sense of propriety and balance, and a need for partnership are expressed through the filter of the two different elements.
