Greek Noun Phrase Word Order

I came across an ordering I had never seen in a Hellenistic text:

τῆς ἐκείνου μεγαλειότητος Diogn 10.5

Has anyone else seen this order before with the demonstrative appearing between the article and the noun?

Did this happen in Classical Greek?

UPDATE: Stephen was kind enough to point out my silly error in the most cordial way possible. For some reason  I missed the gender difference between ἐκείνου and μεγαλειότητος. Oh dear…
