Lotherus (Lother) was one of the earliest kings of Denmark according to Saxo Grammaticus's Gesta Danorum.
Lecturi regem veteres affixis humo saxis insistere suffragiaque promere consueverant, subiectorum lapidum firmitate facti constantiam ominaturi. Quo ritu Humblus, decedente patre, novo patriae beneficio rex creatus sequentis fortunae malignitate ex rege privatus evasit. Bello siquidem a Lothero captus regni depositione spiritum mercatus est; haec sola quippe victo salutis condicio reddebatur. Ita fraternis iniuriis imperium abdicare coactus documentum hominibus praebuit, ut plus splendoris, ita minus securitatis aulis quam tuguriis inesse. Ceterum iniuriae tam patiens fuit, ut honoris damno tamquam beneficio gratulari crederetur, sagaciter, ut puto, regiae condicionis habitum contemplatus.
Sed nec Lotherus tolerabiliorem regem quam militem egit, ut prorsus insolentia ac scelere regnum auspicari videretur; siquidem illustrissimum quemque vita aut opibus spoliare patriamque bonis civibus vacuefacere probitatis loco duxit, regni aemulos ratus quos nobilitate pares habuerat. Nec diu scelerum impunitus patriae consternatione perimitur, eadem spiritum eripiente, quae regnum largita fuerat.
The ancients, when they were to choose a king, were wont to stand on stones planted in the ground, and to proclaim their votes, in order to foreshadow from the steadfastness of the stones that the deed would be lasting. By this ceremony Humble was elected king at his father's death, thus winning a novel favour from his country; but by the malice of ensuing fate he fell from a king into a common man. For he was taken by Lother in war, and bought his life by yielding up his crown; such, in truth, were the only terms of escape offered him in his defeat. Forced, therefore, by the injustice of a brother to lay down his sovereignty, he furnished the lesson to mankind, that there is less safety, though more pomp, in the palace than in the cottage. Also, he bore his wrong so meekly that he seemed to rejoice at his loss of title as though it were a blessing; and I think he had a shrewd sense of the quality of a king's estate.
But Lother played the king as insupportably as he had played the soldier, inaugurating his reign straightway with arrogance and crime; for he counted it uprightness to strip all the most eminent of life or goods, and to clear his country of its loyal citizens, thinking all his equals in birth his rivals for the crown. He was soon chastised for his wickedness; for he met his end in an insurrection of his country; which had once bestowed on him his kingdom, and now bereft him of his life.
