The rune of the day: one rune, one question
Draw one rune with one question held in mind, and read it. That is the whole form, and it is the simplest one there is. The oldest description knows the single lift, but a rune every day is a habit of the twentieth century.
Where this comes from
oldest description Tacitus, Germania, chapter 10 · about AD 98
Tacitus has the priest lift three of the scattered lots, one at a time. The single lift is in his description. The daily rune is not: no text before the twentieth century describes drawing one rune a day.
What the poems say
None of the four witnesses describes a way to cast or read the runes. The poems describe the letters, one by one, and stop there. What each rune means in them is gathered here, rune by rune.
