As usually happens when rummaging through one's grandparents' attic, I unwittingly discovered a seemingly ancient papyrus manuscript. It was stored in an old tin box along with some utensils. I carefully removed and unfolded the paper and this is what I saw: What could it be?
a "cookbook" of sorts! If you replace each element with its symbol (and the two backwards elements with their symbols backwards), you can anagram each group to get an Italian food:
Bi S Te C Ca
F Ag I O Li
La S Ag Na
mA C Ar O Ni
Ra V I O Li
S P Ag H eT Ti
The black shapes above each group are the silhouettes of the food being made.
