Lamenter's Mask

A stone mask twisted into an expression of rapturous grief. Use while disrobed to transform into a lamenter.

The change cannot be undone except by death. Using this mask while already transformed causes the head to swell in size.

This transformation tallies with the state of a denizen of paradise, but the people of the tower denied and hid it from the world. In their foolishness, they viewed true bliss with deep fear.

Lamenting Visage

A stone lantern carved to resemble a lamenting human head, the eyes vacantly beaming out light. Can be raised up when equipped in the left hand, illuminating more of the surrounding area. The unusual expression somehow imparts a sense of contentment. The languid ease of one who needs not sight.

Prattling Pate "Lamentation"

Twisted clay sculpt in the shape of a human head. Emits a blissful "Lamentation".

The voice resounds, seeping into the brain.

Weeping, weeping, weeping. Ever weeping.

Other important points -- all of these items (and the Lamenter himself) are found in the Lamenter's Gaol, one of three gaols where those who will become jar innards are held and tortured before being processed. Additionally, the Lamenter seems to have horns curling back into both his eye sockets.

I see a common thread between these three descriptions. Despite all evidence, we are told that the grieving individual is actually perfectly content. The grief is "rapturous," the blinded Lamenter is experiencing "true bliss," his expression is actually one of "contentment" because he doesn't really need his eyes. Despite the Pate "weeping, weeping, weeping, ever weeping," we are told that this lamentation is "blissful." I don't buy it... And apparently, neither did the Tower Folk. Instead they viewed their creation with fear.

Let's back up a bit. We know that via the means of chopping people up and packing them in jars, the hornsent hoped to create "saints," specifically via rebirth.

Bonny Village Spirit

For pity's sake, your place is in the jar. Nigh-sainthood itself awaits you within. For shamans like you, this is your lot. Life were you accorded for this alone.

Greatjar

A greatjar which fits comfortably over the head when upturned. Attire of the shamans who perform their worship at gaols. Increases the power of thrown pots of all sizes. They offer their prayers to the innards of the greatjars, such that they might be reborn one day into sainthood. This is the cycle of death and rebirth, taken into the hands of mortal men.

(Note: In the first quote, "shaman" is translated from the Japanese "Miko," which consistently refers to Marika's people and could be better translated as "shrine maiden." In the second quote, "shaman" is translated from the Japanese "kitoushi" and connotes something more along the lines of a priest or an elder.) Thank you @drenched-in-sunlight!

We also know that the hornsent see horns as a symbol of the divine, the bigger the better.

Fine Crucible Feather Talisman

A talisman fashioned from thin feathers that embody the aspects of various creatures. Said to have grown on the human body long ago. Improves backsteps but increases damage taken at all times. Hornsent view the Crucible as sacred for the refinement wrought through its evolutionary gifts. Most prominently, their tangled horns.

Horned Bairn

Doll of a tanglehorn bairn. Uses FP to summon vengeful spirits around the caster that autonomously chase down foes. Tangled horns are a symbol of spirituality, but most young born bearing the oversized horns meet a frightfully early demise. These fetishes are made to memorialize them.

Looking at omen in the base game, their horns seem much more chaotic and impractical than those of the hornsent. Most hornsent have a very manageable little crown of horns on their heads, and even the Horned Warrior's horns don't seem terribly impractical. Whereas omen horns seem like they would be both painful and extremely cumbersome.

While the standard omen enemies from the base game don't match the physique of the Lamenter, we do see a few examples of omen with lankier builds. Morgott is obviously larger than a common omen, but his proportions are that of a tall, rangy human. The Sanguine Nobles also seem to be omen, as they have horns that do not appear as part of their armor set.

The more ogre-like omen seem quite similar in build to the bloodfiends from the DLC.

Also, compare Mohg's build to Morgott's (both images sourced from Bonfire VN)

I wonder if the short, broad stature might be a side effect of glutting oneself on the power of the Formless Mother. We know she tends to choose her vassals from among the oppressed, we know that Esgar Priest of Blood was proselytizing in Leyndell's sewers, and we know from the Sacred Bloody Flesh item that the bloodfiends consume her blood as a standard part of their diet. The Sanguine Nobles seem to break the pattern, but they could be newer recruits, or they could be more judicious in their consumption of blood. Either way, we have a few examples (Morgott and the Sanguine Nobles) of omen with a build similar to the Lamenter.

One more point before I start bringing this to a conclusion -- although we only have visual clues to go on with the omen, with the misbegotten we know for a fact that their Crucible mutations come with health complications and cause them a degree of pain. Perfumer Tricia made it her life's work to treat such cases, and in the main game we see many misbegotten in Leyndell who appear to be seeking treatment from other perfumers.

Back to the Lamenter. I proposed in a previous theory (x) that omen might be the product of the hornsents' attempts to produce a "saint." Via the Dungeater's questline, we know it works in concept. By torturing a person in a specific way and doing unspeakable things to their soul, you can cause them to be reincarnated as an omen. I think that's exactly what the Lamenter is -- an early success. A saint.

The problem being, he's in obvious pain. He has horns growing through both of his eyes, and he's constantly wailing. He is everything that a hornsent raised in that culture would aspire to be, and by that same fact he lives a life of constant pain, darkness, and misery.

Of course they reject him. First they try to convince their followers that his weeping is actually an expression of bliss. He's blind because he's too enlightened to need his eyes (think the way the cultists in Midsommar talk about the disabled oracle). When that doesn't catch on, they lock him away and keep trying. It adds yet another twist of tragedy to the atrocities of the Potentates -- sainthood is not a goal just beyond their reach. They've already found it. And after all the innocent lives that they sacrificed to create that saint, they can't stand to look at him.
