22° halo, upper tangent arc, 120° parhelion, parhelic circle in Colonnata, Italy, above the Carrara marble quarries. 12 August 2011
[...] This year was the first day of Pentecost on the nones of June; and on the Tuesday following were seen four circles at mid-day about the sun, of a white hue, each described under the other as if they were measured. All that saw it wondered; for they never remembered such before. (The Peterborough Chronicle, 1104 A.D.)
