The Greek that is translated as “beside himself” or “lost his mind” or other variations in English is (back-) translated by the following languages like this:

• Tzeltal: “his head had been touched” (“an expression to identify what might be called the half-way stage to insanity”)
• Amganad Ifugao: “he acts as though he were crazy”
• Shilluk: “he is acting like an imbecile”
• Shipibo-Conibo: “his thoughts have gone out of him”
• Pamona: “he is outside his senses”
• Indonesian: “he is not by his reason” (source for this and above: Bratcher / Nida 1961)
• Mairasi: “his vision/thinking dried up” (source: Enggavoter 2004)
