Epígrafe

[angelissssshhh]

Que te gusta tanto o por quien este epígrafe está ahí ...

[Rusty]

Without more context, I would say it means:

What you like so much, or for whom this inscription exists ...

-or-

What you like so much, or by whom this inscription exists ...

-or, by a stretch of the imagination-

Who you like so much, or by whom this inscription exists ...



There are many other possibilities. Could more context be provided?

Welcome Angel,

Like Rusty says, if you can provide some more context, we can come up with a good translation.

Agree with Rusty.
First option best, but without context the other two are feasible.
saludos :D
PD: me adelantó Tomisimo...
