Νόησον θάλασσαν πλατεῖαν καὶ ῥηχὴν ἐκτεινομένην, ὕδωρ γλαυκὸν ἠρέμα κινούμενον· πυθμὴν πηλὸς μέλας καὶ ψάμμος κυματώδης, ὑπὸ ῥευμάτων καὶ καταιγίδων σχηματιζόμενος.

Ἐγγὺς δε τῆς ἀκτῆς τὸ ὕδωρ ῥηχότερον καὶ σφοδρότερον· ἐνταῦθα ψαμμώδεις λόφοι καὶ στερεὰ χωρία, ξύλα καὶ φυτικὰ λείψανα ἐκ ποταμῶν φερόμενα.

Ὁ τόπος μεταβάλλεται ἀεί, στάθμη θαλάσσης ἀνιούσης καὶ κατιούσης, ἐν καταιγίδαις τε καὶ ἡσυχίαις.
