Artemidorus, Dream Interpretation 2.15
οἶδα δέ τινα οἰκέτην, ὃς ἔδοξε βατράχοις κονδύλους ἐπισείειν. προέστη τῆς τοῦ δεσπότου οἰκίας ἄρχων τῶν ἐν τῇ οἰκίᾳ ἀνθρώπων· ἡ μὲν γὰρ λίμνη τὴν οἰκίαν ἐσήμαινεν, οἱ δὲ βάτραχοι τοὺς ἔνδον ἀνθρώπους, ὁ κονδυλισμὸς δὲ τὴν ἐπιταγήν.
I know a household slave who dreamed that he struck some frogs with his fist. He was put in charge of his master’s house as the head of the people in the household. For the pond represented the house, the frogs represented the people in it, and the punch represented his command over them.
