The influences on Nabataean architecture are many, from the Assyrian step motif (indeed a favorite of the Nabataeans), to Egyptian obelisks, to classical colonnades. The Nabataeans, of course, threw in their own touches as well. Martha Joukowsky notes in Petra Great Temple that the "broken pediment" of Al-Khazna is characteristic of Nabataean arcitecture.
I believe that the Nabataeans spoke Aramaic or a language like it. Can anyone correct me or flesh out my answer?
The Nabataeans' trade connections brought in goods from the Mediterranaean, Africa, India, and throughout Arabia.
