Answer:
El Greco's work established a foundation for the development of Cubism, a movement in which artists began to abandon a single viewpoint perspective to play with geometric shapes and interlocking planes.
A lancet arch is a window with a pointed arch, these are considered somewhat gothic and often have stained glass or other designs on them. They were used as decoration in churches, castles, ballrooms, etc.
I believe that the instrument Shakira brought back into the mainstream with her hit Whenever, Wherever are the panpipes.
That instrument is a type of a flute consisting of numerous pipes which produce sound when blown into. The name comes from Greek mythology, where the Greek god Pan is often depicted using that instrument. Other than the panpipes, she also used the charango, which is a type of a lute.
Without choices, we are pretty much left on our own. So I will give you what I think and you can take from that whatever you think right.
This painting is filled with interpretable figures. Begin with something easy. Father time begins on the top right and his hand extends over to the top left. The question is what does he represent so much as why is he there? My best guess is that he is suggesting that the two main figures will age, and although they are erotic and desirable now, they soon will not be.
There is a woman on the right whose face looks like a mask. It looks like she will wear one of the masks on the right. Which one will she pick: the red one for warmth or the light colored one which matches the cold lust of the two main figures? We don't know.
There is a young woman who is 1/2 snake with an upper body of someone quite beautiful. I know what she suggests to me, but I don't want to color your opinion. I am a church going person. Consider what I might think. Her face is very innocent, but her body suggests something sinister.
The only one looking on in joy is the young kid behind Venus. He's full of innocence and laughter. If you didn't know better, you would think he's out of place. You're free to say he is. But he is holding what looks like rose hips to me and he's about to throw them on Venus. He is the only thing in the painting that is taking pleasure in what is going on. Contrast him with the figure in the upper middle to left picture screaming. He I think represents the other side of the young kid.
It's a real mixed bag of interpretation. Is this part of a school project? I can't imagine it being so, but I've answered what you asked.
