Picture and Plot

 

Plan of Athens

Coming into Athens from the N or NW you'd get to the agora before reaching the Acropolis. So Dikaiopolis and family must have come from that direction. Maybe they left granddad to rest in the Stoa Poikile, though I think a smaller, less famous colonnade would be a far more likely place

 

Picture

This is not the statue of Athena in front of the Parthenon (whose spear could be seen from afar), but the one inside. She's fully armed and carries the effigy of Victory (the goddess of victory) in her right hand.
Words:  ἡ εἰκών, τῆς εἰκόνος the statue (or image, picture)
      ἐνόπλιος, ον [fully] armed, from ἐν and τὸ ὅπλον the weapon
remember compound adjectives
      ἡ νίκη, τῆς νίκης victory

New is here the active present participle:

   ἐνόπλιος οὖσα:   being fully armed
   Νίκην φέρουσα:   carrying the goddess Victory
Of course. Since both forms go with  τῆς Ἀθήνης, these participles have to follow suit and take genitive form:
   ἡ εἰκὼν ἡ τῆς Ἀθήνης ἐνοπλίου οὔσης 
>   ἡ εἰκὼν ἡ τῆς Ἀθήνης Νίκην φερούσης 

Participles behave like adjectives:

   ὁ νεανίας προσχωρεῖ τῇ καλῇ κόρῃ 
   ὁ νεανίας προσχωρεῖ τῇ κόρῃ πολὺ καλῇ οὔσῃ 
being very beautiful (= because she is very beautiful)

   ὁρῶμεν τὴν καλὴν κόρην 
   θαυμάζομεν τὴν καλὴν κόρην ἀνδρείαν οὖσαν.
being brave (= because she is brave)

We'll deal with active participles: being, eating, drinking καὶ τὰ λοιπά  in more detail after the reading text.



Plot

They get to Athens and find a place to rest their weary feet and watch the bustle of a big town on the eve of a public holday.
The children are hungry, of course. Sausages are always welcome. (What are they called in Greek? and a sausage-vendor?)
Then it's time to do some serious sight-seeing.
See what? And what about old granddad?
When inside the Parthenon, why are the children full of joy and awe at the same time? Are they really afraid?
Why is grandfather in such a foul mood when they at last get back to the portico where they had left him?
