Note 589 — Chapter V

Here we have a serpent which expels and ruins another. In a similar manner, before the times of San Carlo Borromeo, a bronze serpent, which had been carried from Constantinople by the Archbishop Arnolfo in the year 1001, was revered in the basilica of St Ambrose at Milan; some said that it was the serpent of Æsculapius, others that of Moses, others that it was an image of Christ; for us it is enough to remark here that it was a mythical serpent, before which Milanese mothers brought their children when they suffered from worms, in order to relieve them, as we learn from the depositions of the visit of San Carlo to this basilica: "Est quædam superstitio de ibi mulierum pro infantibus morbo verminum laborantibus." San Carlo put down this superstition.
