Hebrew

Ancient Hebrew rarely employed rhyme, e.g., in Exodus 29 35: ועשית לאהרן ולבניו כָּכה, ככל אשר צויתי אֹתָכה (the identical part in both rhyming words being / 'axa/). Rhyme became a permanent - even obligatory - feature of poetry in Hebrew language, around the 4th century CE. It is found in the Jewish liturgical poetry written in the Byzantine empire era. This was realized by scholars only recently, thanks to the thousands of piyyuts that have been discovered in the Cairo Geniza. It is assumed that the principle of rhyme was transferred from Hebrew liturgical poetry to the poetry of the Syriac Christianity (written in Aramaic), and through this mediation introduced into Latin poetry and then into all other languages of Europe.
