Khors is a Slavic god of uncertain functions mentioned since the 12th century. Generally interpreted as a sun god, sometimes as a moon god. The meaning of the theonym is also unknown: most often his name has been combined with the Iranian word for sun, such as the Persian xoršid, or the Ossetian xor, but modern linguists strongly criticize such an etymology, and other native etymologies are proposed instead. Khors is the most frequently mentioned Slavic god, after Perun. He first appears in the Primary Chronicle letopis along with other gods to whom Vladimir the Great erected statues: And Vladimir began to reign alone in Kiev. And he placed idols on the hill outside the palace: a Perun in wood with a silver head and a gold moustache, and Khors, Dazhdbog and Stribog and Simargl and Mokosh. And they offered sacrifices and called them gods, and they took their sons and daughters to them and sacrificed them to the devils. And they profaned the earth with their sacrifices, and Rus’ and that hill were profaned by blood. But God the merciful, who does not wish the death of sinners, on that hill stands today the church of Saint Vasilij, as we will relate later. И нача къняжити Володимиръ въ Кыевѣ единъ, и постави кумиры на хълму, вънѣ двора теремьнаго: Перуна древяна, а главу его сьребряну, а усъ златъ, и Хърса, Дажьбога и Стрибога и Сѣмарьгла и Мокошь. И жьряху имъ, наричюще я богы, и привожаху сыны своя и дъщери, и жьряху бѣсомъ. И осквьрняху землю требами своими; и осквьрни ся кръвьми земля Русьская и хълмъ тъ. Нъ преблагыи Богъ не хотя съмьрти грѣшьникомъ, на томь хълмѣ нынѣ цьркы есть святаго Василия, якоже послѣди съкажемъ. The second source mentioning the god is The Tale of Igor's Campaign: "Prince Vseslav was a judge for his subjects, he distributed cities among princes, but by night he ran like a wolf, from Kiev he ran to Tmutarakan, before the cock crowed, as a wolf he ran along the road of the great Khors." God is also mentioned in the apocryphal work Sermon and Apocalypse of the Holy Apostles, which mentions Perun and Khors as old men, and Khors is credited with real life in Cyprus.
