2. A name for the summer solstice used in many modern Pagan traditions. It has been claimed as the original Pagan name for this festival, but no evidence has been presented to back this up. The actual origin of the term appears to be J.R.R. Tolkien’s fantasy trilogy, The Lord of the Rings; in the calendar Tolkien devised for the fictional race of Hobbits, midsummer’s day is named Lithe.
