In the book Deliverance Lost, from The Horus Heresy,
Corvax is given, by the Emperor himself, the secret of the location of the laboratory where the primarchs were created (or at least somewhere that holds this information, I have not finished it yet). When entering the cave in the mountain, there is some kind of poetry talking about Egypt and Ozymandias, written on the ground/walls.
In real life, there is a poem written by Shelley, called 'Ozymandias'.
While the coincidence seems very unlikely, I am wondering if this is an actual reference to this poem. While I do not know if this is the only existing piece of text that mentions Ozymandias, the content of the text in the book is very different from the real version I linked above.
So my question is: Is this really a reference, as I suspect, to the real 'Ozymandias' poem ?
