Visitors to the Phœnix Park will find in the grounds of the Royal Zoological Gardens a cist, or diminutive cromlech, in many respects similar to that just noticed, which was discovered some years ago in a sandpit immediately adjoining the neighbouring village of Chapelizod. This monument, though not occupying its ancient position, and, notably, a restoration, should be seen by students of Irish antiquities, the stones of which it is composed having been carefully replaced in their original order. It is on record that within this tomb a human skeleton was found, but no mention of anything else it may have contained has been preserved. A much more important example of a removed _Cist_ is now to be seen in the National Museum, Dublin, which should prove of great interest to the student of archæology. In August, 1898, in a sandpit at Greenhills, Tallaght, County Dublin, workmen engaged in removing sand from the face of the pit discovered a cist; it measures 24 inches by 19 inches, and the height in the centre is 19 inches. It is formed of single stones two to four inches thick; the bottom stone is broken. It contained three vessels--a large urn inverted and covering a much smaller one, and a food-vessel of flower-pot shape. Under the urn was a quantity of burnt bones. Other urns and broken fragments of pottery, a skeleton, and portions of burnt bones were found in the same pit, which shows that both forms of disposing of the dead existed at the same period of time. The cist, encased in its matrix of sand and earth, was carefully and most successfully removed by Colonel Plunkett, director of the Museum, and his assistants. Expert opinion on the shape and decoration of the vessels places them at the close of the Bronze Period.[33] * * * * * [Illustration: Cromlech in Howth Demesne.]
