Etymology
From Hebrew מְטַטְרוֹן (Məṭaṭrôn), whose origin is obscure. Possibly from Hebrew מטרא (mattara) 'keeper of the watch.' The Greek/Latin form superficially appears to be a Greek compound meta-τρον (-tron), but that would not seem to make much sense semantically, meaning something like "among-tool." It has also been proposed that the Hebrew word actually does in turn originate from Greek, coming from μετά + θρόνος, with the "th" being transformed into a "t" as the word was repeatedly taken up by one language from another. A review by Hekhalot lists these two possibilities plus seven more.
