Zodiac is a Greek word that has twelve divisions to it that are known as astrological signs. Each of these signs represents different things and is based on various birthdates. The Roman era was the time when the zodiac starting being used. However, in today’s time, the zodiac is more commonly associated with astrology. If you choose to get a zodiac tattoo, this will likely be your astrological sign. If so, the tattoo selected will be based on your birthday. Some of the tattoos designs offered in this category include Aquarius, Libra, Cancer, Capricorn and Libra to name a few. Each one represents something different. For instance, a zodiac Aries tattoo would be a ram tattoo or birth sign symbol.
