Final answer:
The references provided discuss various meals in historical and literary contexts, but do not mention the Evers receiving lunches from nymphs. They illustrate society's relationship with food and wealth in different eras.
Step-by-step explanation:
The passages you've provided from various texts describe different scenarios involving food and mealtime, though none of them specifically mention the Evers receiving their lunches from nymphs. The references to meals show a historical or literary portrayal of food consumption such as indulgence in luxurious items like fish eggs and truffles, or the simple pleasure of a home-cooked breakfast. Whether it's the social implications of extravagance in Polybius' account, the delightful satisfaction of a clam chowder picnic, or the disapproval of Cato regarding the financial priorities of the youth, these meals symbolize more than mere sustenance.
