Jupiter Ammon

Sal amioniak, ammonium chloride (originally sat armeniaCy from its occurrence in Armenia, changed later to sat ammmiaCy owing to its confusion with natron, or sodium sesquicarbonate, found near the temple of Jupiter Ammon in Libya). 

The Egyptian national god Amen was known by the Romans when they conquered Egypt as Ammon, and identified by them with their god Jupiter. Outside the Egyptian temples the refuse from the sacrifices, etc, gradually disintegrated and parts were converted into mineral salts, which became known as salts of Ammon . In course of time it was found that these salts were mixtures, part being volatile. The name Ammon was retained for these volatile portions which are now termed ammonia or ammonium salts.
