Behar-Cohen et al. notes the periphery of the cornea has a focusing effect:


  UVR incident from the periphery is refracted into the eye, and due to the focusing effect of the cornea, UV radiation is on average 22-fold stronger at the nasal limbus, which is the typical site for pterygium and pinguecula. Moreover, UV radiation is on average eight times stronger at the nasal lens cortex, the typical site for cortical cataract.


Authors note this in further papers as peripheral light focusing. Essentially, the light is refracted from the periphery of the cornea into the anterior segment of the eye. By this notion, I'd say indirectly looking at the sun is no less damaging than directly looking at it (given there are no other restrictions, such as special lenses, etc.).

Is it safe to look indirectly at the Sun?
I want to make a historically accurate biblical meal for a group. I'm using chicken, and serving it with flatbread and an Israeli salad (sans tomatoes and other new world vegetables)

Does anyone have a recipe for a historical barbecue chicken or an idea of what sorts of spices were used back then?

edit: Just thought I'd let you guys know

I marinated the chicken in a mixture of rosemary, thyme, oregano, toasted sesame, garlic, salt and a bit of mint/pepper overnight. Then put them on skewers. Maybe not 100% authentic, but tasty.
