Is the old man Mercury in the astrolabe his predecessor?

The astrolabe Mercury means the former. Old people generally have three meanings: first, friends from a long time ago. The other is an ex-wife or someone who once loved each other. Du Fu: "All he can see is the smile of his new sweetheart. I can't hear the old man crying." There is also an old minister who is old and virtuous and has stayed in his position for a long time. In astrology, Mercury belongs to the "personal planet" in the astrolabe. It is the ruler of Gemini and Virgo. In Roman times, Mercury was the god representing merchants and the patron saint of thieves, and was regarded as all quick-witted and agile machines. Mercury rules human thoughts and language expressions, human nervous system, hands, back and fingers. The astrolabe Mercury is his predecessor.
