To piggy back this, was there any notes or ingredients used back then that we still use today?

There are surviving clay tablets from the 2nd Millennium B.C. which detail the process of making perfumes. One such recipe calls for myrrh, calamus, and cypress. Musk was also known to be suggested as a base. So we see recipes commonly called for ingredients still used today, even including those ingredients which do not themselves necessarily smell nice but which merely help with the creation of the perfume (and which are still in use today) such as ambergris. Even the overall process has changed very little from the instructions outlined in these texts.

So, in short, though I couldn't say as I know exactly how these ancient perfumes smelled, I imagine we've all smelled something remarkably similar to them in our lives.

EDIT: I should probably note that the clay tablets I referenced are Babylonian.

And how in the world would ancient perfumers ever have gotten the idea that old whale shit would function as a fixative in perfumes?
