Montes Serrorum is a mountain somewhere in the Carpathians mentioned by Roman soldierAmmianus Marcellinus regarding events in the Gothic War. In 367, the Roman Emperor Valensattacked the Thervingi north of the Danube river. However, he was unable to hit them directly, because apparently the bulk of the Goths retreated to the Montes Serrorum. Marcellinus says that Valens could not find anyone to fight with and even implies that all of them fled, horror-struck, to the mountains. It was described as only accessible to "exceedingly" familiar with the surroundings, thus the Roman troops were unable to achieve anything.
Dispute
The mountain was probably located in the Southeastern Carpathians. Matei Cazacu tried to precisely locate it to the Siriul mountain range that divides Transylvania from Wallachia - the Buzău Mountains. Wanke was sceptical to Cazacu's attempt. There were attempts to etymologically deriveSiriu from Romanian, Hungarian and Turkish language. The toponym has been connected to the Sarmatian tribe Serri settled north of the Caucasus, mentioned by Pliny the Elder in Naturalis Historia. Other considered an existence of another same-named Dacian tribe because were recorded Thracian words with the same root. Although by some it seems unlikely, the majority of scholars deem the Sarmatian tribal connection as the most credible explanation because it is also similar to other ancient names of the Carpathians, Sarmatian Mountains and Alpes Bastarnicae, the fact Marcellinus reported about the Caucaland referring to the Carpathians, making Montes Serrorum a made-up geographical name. Konstantin Jireček also connected the toponym with Pliny's Serri, but according to him they were "Caucasian Serbs". Slovene anthropologist Niko Županič treated the toponym as evidence of "Serb presence in Dacia", and this view was supported by Ivo Vukcevich, but the fringe theory in turn was discredited by Florin Curta for being based on a "dubious etymology". The toponym Montes Serrorum in another version of the manuscript is written as Montes Succorum, however, although the root "suc-" is reported in several toponyms of the time in the region, the form is a result of writing error.
