Whose ruins were used by the artists?

In their articles "Rwinsta. Dreamers or realists"
"The pyramid of paintings by artists of 17 - 18th century. The pyramid of Cestius in Rome and other piramidy."
I showed pictures of artists with all sorts of ruins and pyramids.

Traditional historians believe. that most of the depicted never existed.
That is, the artists saw the Forum, Colosseum, pyramid of Cestius, and just put them on all sorts of landscapes.
But then we had to see ALL the paintings the same ruins. For example here are.

Here we can say that Paolo Panini collected on the same landscape a few friends on the ruins.

And when we see the ruins quite well, strangers? It's easy to say "they imagined". As you can imagine and then draw it to the smallest detail, NEVER really seeing.
Draw a colossus of Helios, for example, or the hanging gardens of Babylon.

Here's an example of imagination of artist.

Where something like that was seen by the artist? The pyramid in the background without the top. If it's the pyramid of Cestius, why not draw with the correct top?

Here is a picture of a very real kind.

It seems that Claude gellet (1600 - 1682) painted what he saw. You can compare with photos.

And now another picture of this artist.

Where copied?

Here again is clearly a collective picture.

There's only one problem. What kind of column with a monument near the building like the Pantheon?
Here is another picture of a pyramid without the top.

There are two artist came up with this pyramid? Or each other's sketched?

A distinctive feature of ALL the ruins is the apparent gigantism.

And now thinking aloud.
All the same, if you count ruins it is real, it begs the logical conclusion.
The people who lived in these buildings were much taller than modern man.
It can be seen in the picture Robert.

Floor height and door openings are clearly aimed at different height.

I have the feeling that young people came into these homes and began to live.

There was a race of giants with advanced technology, and then disappeared.
The pyramids have served as a kind of transmitter of energy.
What energy you can collect from the atmosphere and transfer to the distance proved Tesla.
And maybe he even did it.

And our ancestors probably were just cheap labor the race of giants. Miners, ranchers and so on. So the technology of this civilization we don't know.

And where he could get giants, I will write in another post.
