The planting of yew trees in Churchyards in Wales is as old as the Churchyards themselves; and it is probable that they were originally intended to act as a screen to the Churches by their thick foliage, from the violence of the winds, as well as a shelter to the congregation assembling before the church door was opened. The first Churches in Wales were only wooden structures, and needed such screens much more than the comfortable stone Churches of the present day. Another important object in planting the yew was to furnish materials for bows, as these were the national weapons of defence. The Churchyards were the places where they were most likely to be preserved, and some authorities derive the English word "yeoman" from yewmen, that is, the men who used the yew bow. The yew bow was very common throughout Wales in the old times, and skill in archery was universal in the country; and as late as Tudor times, the Welsh poet, Tudur Aled, asks, in lamenting the death of a squire:-- "Who can repeat his exploits to-day? Who knows so well the strength of yew." In the memorable Battle of Cressy, three thousand five hundred Welsh archers followed the Black Prince in the attack on France in the year 1346, and as many more came from the Welsh lordships, and bore such distinguished parts, for the success of this war was due to the skill of the Welsh Archers, and at the end of the battle the Prince adopted the motto, "Ich Dien," which has been the motto of the Princes of Wales ever since. Evelyn's opinion is "that we find it (the yew) so numerously planted in Churchyards from its being thought a symbol of immortality, the tree being so lasting and always green." There are at the present day in the Churchyards of Carmarthenshire and Cardiganshire, some fine specimens of the yew tree, and some of them hundreds of years, if not nearly a thousand years old. In former times when Churchyards were resorted to for recreation, seats were fixed round the trunk of the tree. Many of the Churchyards in Wales in ancient times, before the introduction of Christianity, had been Druidical circles. This is evident from the oval form of the ground of many of them, which often resemble small embankments, or mounds. Such is the case as regards Tregaron Church, in Cardiganshire, Llanddewi Brefi also is on elevated ground, as well as several other Churchyards.
