Two Artefacts in a Lebanese Collection

I was looking at an old article about the Jawad Adra collection and spotted these:

This Palmyrene relief was broken into fragments, which certainly makes the object more portable... how did it enter the market? Who has the missing head?

And what about this odd thing? Has it any ''grounding?

Does it not have a hint of some of the Brooklyn Museum objects to it? Where and when was it bought, and how did it enter the market?
