156a ως

[Constantinus Philo]

ἀρχὴ δέ, ἐξ ἧς καὶ ἃ νυνδὴ ἐλέγομεν πάντα ἤρτηται, ἥδε αὐτῶν, ὡς τὸ πᾶν κίνησις ἦν καὶ ἄλλο παρὰ τοῦτο οὐδέν
is this ὡς like ὅτι? then it depends upon an implied verb of speaking.

[bedwere]

I think it means "as", explaining what ἀρχὴ means.

[Constantinus Philo]

you may be right, so it is like 'like'

[Constantinus Philo]

still i think it belongs to Smyth 3001ως with verb implied
