- Rubeus Hagrid: "That night a fight broke out, we saw it from the mouth of our cave, lookin' down on the valley. Went on fer hours, yeh wouldn' believe the noise. An' when the sun came up the snow was scarlet an' his head was lyin' at the bottom o' the lake."
- Hermione Granger: "Whose head?"
- Rubeus Hagrid: "Karkus's. There was a new Gurg, Golgomath. Well, we hadn' bargained on a new Gurg two days after we'd made friendly contact with the firs' one, an' we had a funny feelin' Golgomath wouldn' be so keen ter listen to us, but we had ter try."
- — Hagrid discusses the new Gurg[src]
Very little of Golgomath's history is recorded. He beheaded the Gurg of the colony, Karkus, and assumed leadership of the giants. He also took Karkus' helmet, which was a gift from the envoys of Albus Dumbledore.
When Rubeus Hagrid and Olympe Maxime decided to continue with their negotiations where they left off with Karkus, with a roll of dragon skin, Golgomath ordered two giants to lift Hagrid up, which resulted in Madame Maxime attacking them with magic, an act that brought their negotiations to an end.
Golgomath also favoured the Death Eaters when they came to the colony to persuade the giants to rejoin Lord Voldemort's forces. Golgomath and the Death Eaters' envoy, Walden Macnair, got along very well, as they both loved to kill. Macnair and another Death Eater had been consorting with Golgomath for some time, visiting and offering gifts. Golgomath told Macnair about Hagrid and Madame Maxime being there, and eventually allied the giants with Lord Voldemort, and ordered his underlings to raid the caves of the valley for giants who didn't agree with Golgomath's leadership.
It is unknown whether Golgomath was among the giants that fought at the Battle of Hogwarts, but given his status as Gurg, it is highly probable that he was. His ultimate fate following Voldemort's defeat is also unknown: he may have either returned to his position as Gurg, been challenged and defeated by another giant, or else been killed during or after the war for allying with the Death Eaters.
He was one of the biggest giants among his colony, being about twenty-five feet tall, with matching black teeth and a necklace of bones, some of which looked like human bones.
Personality and Traits
Like many of his kind, Golgomath was a savage and ferocious-mannered Giant. He was also a powerful warrior and had a desire to slaughter others. He did also get along with Death Eaters, especially the equally murderous Walden Macnair.
Golgomath's name is derived from the number "googol." Its numerical value is a single digit 1 with one hundred zeros afterwards, or 10100. Obviously, this is a huge number, which is fitting for one of the largest of the giants. An alternative would be Golgotha or Calvary, the hill outside Jerusalem on which Christ was reputedly crucified. The name means "(place of the) skull", gulgulta in Aramaic with the Hebew cognate being gulgoleth. The Ancient Greek manthano, from which math is derived, means "learn" or "be taught", so together the bearer would have "learn(t) in the place of the skull (death)", which would seem, to sum up this tiny, enclosed valley.
