Objects with rotational symmetries, which we’ll call “mandalas”, occur in many cultures. The mandala gallery will show some examples. 
To celebrate St. Patrick’s Day, here are two Celtic crosses. The first is from the Gallarus Oratory in Ireland, and has symmetry type D4. The second one, which is a Z4, is from Santiago de Compostela in Spain.

I traveled to Dublin a few years ago and had a wonderful experience. My ancestors on my Father’s side immigrated to American from Ireland during the potato famine. I will post an image of a mandala I saw there during my visit. — Michael Blaine
