I'm not sure if this statue predates the fortress or not, and whether it appeared before or after the zone was sealed by the Tevinter, whether it predates the Hakkonites and Ameridan breaching in or not. The entire zone has codex entries about a "hole in the mountain" which could be the actual Lowland fortress crater, caused by either an earthquake giving way for Darkspawns to fight Grey Wardens and Avvars, or by the stirring of "something big" deep beneath the earth, which could be either an Archdemon (Razikale?), the High Dragon that was used as a receptacle for Hakkon, or... this "Crying Titan".
Since we've also got a note from the Forgotten One Geldauran in the Basin, and how he planned to become a God in his own capacity, I have no idea what to think.
The conspiracy theory codex entries Mysteries of the Basin clearly don't help:
I speak of Orlais' attempts to rouse the Snake Kings of the Earth against Tevinter's alliance with the Moon Men.

If one looks keenly, once can see the Frostback Basin must have been manipulated by the hand of some Vast Thing. The crater in the Lowland Fortress was not the natural settling of mountains, but came to exist after the shifting of Something Below Ground! The Snake-Kings must be vast, and their movements powerful to cause the Earth to Quake with their moving. It is Clear as the Sky that Ancient Tevinter, along with the Moon Men, came here to make an Attempt to kill a buried Snake-King under the crater!!! Too many Signs and Portents are aligned to think anything else.
This might make you think he could somehow have a point, but then you read the source he quotes: "Whalen Vankin". And then you google that, you slowly take a few steps back and you say a word.
Not convinced? He also quotes Ser Ycke. I now believe he meant Icke.

And now I can hear Bioware talking to me through the game. They are telling me of the song, of the thought. The tinfoil hat doesn't block it anymore. But I must keep going. I shall find out the Truth. For all my predecessor. For all of us.
