1. The background

	Greek gods are not friends. Long time ago, there was a big war between two of them : Athena and Poseidon. Here is Athena, the goddess of wisdom.
Here is Poseido, god of the seas,  Why are they disputing?
	They are fighting for domination over Athens. Athena wins because she gave olive tree to Athens. Here you see some olives.
They argue about Odysseus. Poseidon doesn't like the Trojans, but he doesn't really like the Greeks either.  He was rather indifferent to Odysseus, until Odysseus attacked one of his protected: Polyphemus. Odysseus deceives and blinds Polyphemus, which will bring him many storms. Here you can see the head of Polyphemus the Cyclops.
	Poseido was in love with Medusa.  Perseus killed Medusa and bring her head to Athena. Here you can see Athenas shield, with the head of Medusa.
The most unpredictable episode is with Laocoon.  Laocoon was a priest of Poseidon. He didn't want the Trojans to accept the Wood Horse.  But Poseidon sent him and his sons serpents and killed him!

2. The gameplay

Antique coin		Owl mesh
	Why are the owls so important ?  Owls are Athena's favorite animals. Athena is order. Poseido is disorder. Athena owns the owls. Poseido owns the sea. All the owls ran away. Your boat is stranded. You have to find them all.
	The greatest danger in the game comes from the sea. You risk falling into the sea very often. So you will die.  Now, who is the god of the sea?

Homer, Iliad, XV

τὴν δὲ μέγ᾽ ὀχθήσας προσέφη κλυτὸς ἐννοσίγαιος·

185 ὢ πόποι ἦ ῥ᾽ ἀγαθός περ ἐὼν ὑπέροπλον ἔειπεν

εἴ μ᾽ ὁμότιμον ἐόντα βίῃ ἀέκοντα καθέξει.

τρεῖς γάρ τ᾽ ἐκ Κρόνου εἰμὲν ἀδελφεοὶ οὓς τέκετο ῾Ρέα

Ζεὺς καὶ ἐγώ, τρίτατος δ᾽ Ἀΐδης ἐνέροισιν ἀνάσσων.

τριχθὰ δὲ πάντα δέδασται, ἕκαστος δ᾽ ἔμμορε τιμῆς·

190 ἤτοι ἐγὼν ἔλαχον πολιὴν ἅλα ναιέμεν αἰεὶ

παλλομένων, Ἀΐδης δ᾽ ἔλαχε ζόφον ἠερόεντα,

Ζεὺς δ᾽ ἔλαχ᾽ οὐρανὸν εὐρὺν ἐν αἰθέρι καὶ νεφέλῃσι·

γαῖα δ᾽ ἔτι ξυνὴ πάντων καὶ μακρὸς Ὄλυμπος.

τώ ῥα καὶ οὔ τι Διὸς βέομαι φρεσίν, ἀλλὰ ἕκηλος

195 καὶ κρατερός περ ἐὼν μενέτω τριτάτῃ ἐνὶ μοίρῃ.

χερσὶ δὲ μή τί με πάγχυ κακὸν ὣς δειδισσέσθω·

θυγατέρεσσιν γάρ τε καὶ υἱάσι βέλτερον εἴη

ἐκπάγλοις ἐπέεσσιν ἐνισσέμεν οὓς τέκεν αὐτός,

οἵ ἑθεν ὀτρύνοντος ἀκούσονται καὶ ἀνάγκῃ.

Pseudo-Apollodorus, Bibliotheca 

[3,14,1] Κέκροψ αὐτόχθων, συμφυὲς ἔχων σῶμα ἀνδρὸς καὶ δράκοντος, τῆς Ἀττικῆς ἐβασίλευσε πρῶτος, καὶ τὴν γῆν πρότερον λεγομένην Ἀκτὴν ἀφ᾽ ἑαυτοῦ Κεκροπίαν ὠνόμασεν. ἐπὶ τούτου, φασίν, ἔδοξε τοῖς θεοῖς πόλεις καταλαβέσθαι, ἐν αἷς ἔμελλον ἔχειν τιμὰς ἰδίας ἕκαστος. ἧκεν οὖν πρῶτος Ποσειδῶν ἐπὶ τὴν Ἀττικήν, καὶ πλήξας τῇ τριαίνῃ κατὰ μέσην τὴν ἀκρόπολιν ἀπέφηνε θάλασσαν, ἣν νῦν Ἐρεχθηίδα καλοῦσι. μετὰ δὲ τοῦτον ἧκεν Ἀθηνᾶ, καὶ ποιησαμένη τῆς καταλήψεως Κέκροπα μάρτυρα ἐφύτευσεν ἐλαίαν, ἣ νῦν ἐν τῷ Πανδροσείῳ δείκνυται. γενομένης δὲ ἔριδος ἀμφοῖν περὶ τῆς χώρας, διαλύσας Ζεὺς κριτὰς ἔδωκεν, οὐχ ὡς εἶπόν τινες, Κέκροπα καὶ Κραναόν, οὐδὲ Ἐρυσίχθονα, θεοὺς δὲ τοὺς δώδεκα. καὶ τούτων δικαζόντων ἡ χώρα τῆς Ἀθηνᾶς ἐκρίθη, Κέκροπος μαρτυρήσαντος ὅτι πρώτη τὴν ἐλαίαν ἐφύτευσεν. Ἀθηνᾶ μὲν οὖν ἀφ᾽ ἑαυτῆς τὴν πόλιν ἐκάλεσεν Ἀθήνας, Ποσειδῶν δὲ θυμῷ ὀργισθεὶς τὸ Θριάσιον πεδίον ἐπέκλυσε καὶ τὴν Ἀττικὴν ὕφαλον ἐποίησε.
