It only remains to ask, Why was the mistletoe called the Golden Bough? The name was not simply a poet’s fancy, nor even peculiarly Italian; for in Welsh also the mistletoe is known as “the tree of pure gold.”(938) The whitish-yellow of the mistletoe berries is hardly enough to account for the name. For Virgil says that the Bough was altogether golden, stem as well as leaves,(939) and the same is implied in the Welsh name, “the tree of pure gold.” A clue to the real meaning of the name is furnished by the mythical fern-seed or fern-bloom. We saw that fern-seed is popularly supposed to bloom like gold or fire on Midsummer Eve. Thus in Bohemia it is said that “on St. John’s Day fern-seed blooms with golden blossoms that gleam like fire.”(940) Now it is a property of this mythical fern-seed that whoever has it, or will ascend a mountain holding it in his hand on Midsummer Eve, will discover a vein of gold or will see the treasures of the earth shining with a bluish flame.(941) And if you place fern-seed among money, the money will never decrease, however much of it you spend.(942) Sometimes the fern-seed is supposed to bloom at Christmas, and whoever catches it will become very rich.(943) Thus, on the principle of like by like, fern-seed is supposed to discover gold because it is itself golden; and for a similar reason it enriches its possessor with an unfailing supply of gold. But while the fern-seed is described as golden, it is equally described as glowing and fiery.(944) Hence, when we consider that two great days for gathering the fabulous seed are Midsummer Eve and Christmas—that is, the two solstices (for Christmas is nothing but an old heathen celebration of the winter solstice)—we are led to regard the fiery aspect of the fern-seed as primary, and its golden aspect as secondary and derivative. Fern-seed, in fact, would seem to be an emanation of the sun’s fire at the two turning-points of its course, the summer and winter solstices. This view is confirmed by a German story in which a hunter is said to have procured fern-seed by shooting at the sun on Midsummer Day at noon; three drops of blood fell down, which he caught in a white cloth, and these blood-drops were the fern-seed.(945) Here the blood is clearly the blood of the sun, from which the fern-seed is thus directly derived. Thus it may be taken as certain that fern-seed is golden, because it is believed to be an emanation of the sun’s golden fire.
