The origin of the urns

Tiwaz

Looking at some pictures I noticed something. The letters on the urns do not match the ones on/in the Engineer-buildings or the Engineer-cryotubes. 

Why? Does that mean they didn't make them? Using two different sets of letters doesn't make much sense to me in this case.

Or is it just another oversight? 

I don't know if this has been addressed before.

Maybe the Engineers use different alphabets for different aspects of their society.

The alphabet on the urns/vessels could be a 'war' alphabet, only to be used by Engineers on bombing missions and those who manufacture weapons.

The alphabet on the buildings/cryotubes could be a general alphabet used as instructions/directions for Engineers to read and understand the technology to be used/importance of the buildings they are in.

Wasn't the Engineer language supposed to be something similar to Sumerian, in the deleted scene of David talking to the Engineer?  The characters on the wall by the dead bodies reminds me of cuneiform, which would match with Sumerian spoken language.  Not that this answers your question, but maybe the writing on the urns (with the swoops and slashes) is not from the Engineers.

Or maybe it's just like different fonts; the fancy cursive on the urns, and the big bold block style font for warnings or instructions lol.

The urns were stolen from the 'Gods', so they may have different script/language on them?  That would be my guess?

CB, that'd be my guess too.

Well, the Engineers are likened to Titans and Dark Angels rather than Gods. Since that's unlikely, it could be the syntax programmable language (remember how the black goo is said to be "fiendishly inventive?") It need not look like C++ ... because, well, that's digital (and primitive). Or maybe it is the chemical formula for whatever is in it.
