Trajan and Goudy Trajan are commercial fonts and you need to pay to use them.
Optimus Princeps is free for personal use (I'm not sure about commercial use, better ask the designer...)

It's for personal use.
Thank you, but Optimus Princeps is not the same than Goudy Trajan... :(
Does it exist a copy of it (Goudy Trajan) free?
Like I said before, Goudy Trajan is a commercial font, so if a free version of it exists, using it would be illegal (even for personal use).
I believe Optimus is as close as you will get.
Well I'll be damned! Look what I found :

Why?...
You mean 'Why not Trajan'? or 'why is Goudy Trajan free'?
I meant the second one, but it's not free indeed, wrong change...

Ah! I didn't click the link... But, there's is still a free trial version that 'does not include small caps, discretionary ligatures, swash alternates, Cyrillic, Greek, or fleurons.'
Ohhh thank you! It's perfect!
