Graves used the work of Duald MacFirbis (1585 – 1670) the scholar and bard of clan O’Brien and bard Roderick O’Flaherty (1629 – 1718). There is doubt among modern scholars as to whether these sources are enough as there is evidence that some of the terminology used has Latin rather than Celtic roots and it is unlikely Christian bards would have sought to preserve ancient Druid knowledge.
Helena Peterson has provided an alternative Celtic Zodiac. It uses the planets Uranus, Neptune and Pluto which the Druids where unlikely to have discovered but her book The Handbook of Celtic Astrology* (USA *) remains popular.
Due to the competing versions of the Celtic Zodiac and the on-going debate around accuracy it is easy to find tables with differing dates.
