Venus laments that she suffers twice, first because he will not speak to her, and second because when at last he does, it is to scold her. She says:
Thy mermaid's voice hath done me double wrong;
- line 429
The Greeks had, in their myths, tales of beautiful young women, called sirens, who rested on the rocks of a seashore and sang in heavenly voices. Sailors passing by would be attracted by them and, steering their boats nearer, would meet death upon the rocks.
Originally sirens may have been wind spirits carrying off the souls of the dead, and were sometimes pictured with birds' bodies. However, the wind was more deadly on sea than on land, and the sirens became more and more closely associated with the sea until they were pictured as creatures who were women down to the waist and fish below that.
These are the "mermaids" ("sea-maids"), who bewitch sailors to their doom on the rocks, as they sit combing their long hair and singing. The famous German poem "Die Lorelei" is of such a creature.
So when Venus speaks of Adonis' "mermaid voice" she means a beautiful voice that is luring her to doom.
... worse than Tantalus'.. .
The day is drawing to a close and Adonis finally manages to get Venus to promise to leave him alone if he kisses her. He proceeds to do so but she returns the embrace in such full measure that he has all he can do to disengage himself. He then reveals that the next day he intends to hunt boar.
At this Venus is sent into a paroxysm of fear, lest he be killed in so dangerous a pursuit. She seizes him and they fall to the ground in the very position of love. Yet even so, to Venus' frustration, he will do nothing.
That worse than Tantalus' is her annoy To clip Elysium and to lack her joy.
- lines 599-600
Tantalus was a Peloponnesian king who was an intimate friend of Jupiter and the other gods. He was admitted to their feasts and in return he invited them to his house. For some reason, perhaps to test their divine knowledge, he served them the flesh of his own son when they were feasting at his house. The gods were horrified. They restored the son to life, and, for his detestable crime, Tantalus was killed by Jupiter's lightning bolt. What's more, Tantalus was sent to Tartarus, the region beneath Hades where particularly wicked people were specially punished.
Tantalus' punishment was to stand in water up to his neck in eternal frustration. He was consumed by thirst, but every time he stooped to drink, the water swirled downward. Fruit-laden branches hovered temptingly near and he was famished, but every time he reached to snatch a fruit, it whisked away. It is from this that the word "tantalize" is derived.
For Venus, to have Adonis exactly where he ought to be and yet have him make no use of the fact seems a frustration worse than that of Tantalus. She was in Tartarus, even though she was "clipping" (holding) Elysium, which was the Greek version of Paradise.
In the Homeric writings, Elysium or "the Elysian plain" existed in the far west, the dimly explored (and therefore wonder-filled) western regions of the Mediterranean Sea, where heroes were taken after death to live in eternal bliss. By later writers this had to be transported beyond the ocean rim, for explorers reached the westernmost point of the Mediterranean shores without finding Elysium. The Greek poet Hesiod, writing a century after Homer, speaks of "the Islands of the Blest" lying out in the Atlantic.
As geographic knowledge continued to broaden, the Roman poet Vergil, writing six centuries after Hesiod, was forced to move Elysium underground, making it a portion of Hades devoted to delight. It was suffused with an eternal spring. Its flowers, groves, and fountains were lit by soft sunshine during the day and by the familiar constellations at night. Then the righteous, resting on banks of resilient and perfumed flowers, lived in never-ending felicity.
... modest Dian ...
Venus urges Adonis to hunt foxes or hares, anything that is not dangerous, rather than boars. Adonis, having paid his kiss, finds that he still cannot disengage himself from her wild grasp. It is night already and he is annoyed at this, for it will be hard to find his way. Venus turns this too into praise of Adonis' beauty.
