"Now, they the Argonauts sailing the through sea of Marmara suddenly saw Glaukos , the sage spokesman of the sea-god Nereus, emerge from the salt-depths."
Along with Jason and Herakles, Glaukos is another mortal who achieves immorality. He was only a fisherman but transformed into a sea-god and became the protector of fishermen. He is described as a merman.
Asteroid Glaukos can show an extraordinary interest in the sea or maritime and an affinity with divination as well. If he is conjunct Venus or the Seventh House ruler he may show a partner or lover who are related to the sea, fishing or sailing. He brings the touch of the merman wherever he shows himself.
