Silver Wain
From Tolkien Gateway
One of the names of the Great Bear in the poem Kortirion among the Trees (= KT), written by J.R.R. Tolkien in November 1915 and later revised in many instances until the final version, now titled The Trees of Kortirion (= TK) was composed, according to Christopher Tolkien, "nearly half a century after the first" (LT1, 39).
KT III,119-121: The seven candles of the Silver Wain, / Like lighted tapers in a darkened fane, / Now flare above the fallen year. (LT1, 39)
TK III,120-121: The funeral candles of the Silver Wain / Now flare above the fallen year. (LT1, 43)
