"How much do olives and cookies cost?"
Translation:Quanti olivae et crustula constant?
Same etymology. Crusty from "crust", from the French Croûte (old French crouste), gave the French adjective "croustillant" meaning crusty.
It seems like dry crusty biscuits here! (However they would probably be surprised to find that weird brown thing called chocolate in it)
Crusta, in Latin, is everything that would wrap or cover something, to envelop.
Crusta luti, is a layer of mud (from lutum)
Crusta panis is a bred crust (I think it's the meaning that is interesting here)
Crusta piscium is the fish scales.
Crusta (feminine) is, thus, a crust, and crustula is a small crust ("ula" as a diminutive), and crustulum, is a small crustum (neuter).
Crustum is given in the dictionary as crunchy food: cake or biscuit.
Crustulum, a small crustum, a delicacy. a confection, sweetmeats.
Not a weird pairing, it's food, any food bought together is ok and logical for me.
I've found a recipe of ancient Roman biscuits/crustula, with honey and sesame seeds.
I found a recipe online http://zeitgeist.exarc.net/manuals/cooking-crustulum-and-dulcia-domestica-roman Crustulum seems to be more like a thick pancake or muffin and closer to the American meaning of a biscuit than what we commonly think of now as cookies . The thing it is cooked in actually sounds a lot like a muffin tin only rather than baked its used as a griddle over a fire. I think if you have it with olives, the olives woulf actually go into the batter to be cooked.
Thanks for sharing! Apple raisin crustula sound really quite nice, and I'm sure a savory version with olives would work well, too. :q What with the special tin, I think they look remarkably like Dutch poffertjes: https://en.wikipedia.org/wiki/Poffertjes I wonder if there was any use of leavening agents in Roman baking?
This recipe is now found here: http://openarchaeology.info/manuals/cooking-crustulum-and-dulcia-domestica-roman
"Olivas" is plural accusative; you use it when the olives are the direct object in the sentence. "Olivae" is plural nominative; you use it when the olives are the subject of the sentence. ("Olivae" also happens to be singular dative, but that's a clearer distinction.)
Since the olives are part of the subject of the sentence (we could rephrase it as "Olives and cookies cost how much?"; the olives and cookies are what are performing that verb of costing), we need the nominative form "olivae."
It's genitive singular, with the implication of something like "quanti pretii" ("Of how much price do cookies and olives cost?").
"Quot" or a non-genitive "quantus/quanti" would be asking about how many cookies and olives there are, and wouldn't make much sense with "constant."
