Mosheh ben Yaaqov ibn Ezra, (or Moses ibn Ezra, Arabic: أَبُو هَارُون مُوسَى بِن يَعْقُوب اِبْن عَزْرَا, Hebrew: מֹשֶׁה בֵּן יַעֲקֹב הַסַּלָּח אִבְּן עֶזְרָא) (ca. 1055-after 1138) born in Granada, was an Andalusian Jewish rabbi, philosopher, linguist, and poet known as Ha-Sallaḥ (for the seliḥot he composed). Moses Ibn Ezra is considered to have had great influence in the Arabic literary world and is considered one of Spain's greatest poets and was considered ahead of his time in his theories on the nature of poetry. One of the more revolutionary aspects of Ibn Ezra's poetry that has been debated is his definition of poetry as metaphor and how his poetry illuminates Aristotle's early ideas. The importance of ibn Ezra's philosophical works was minor compared to his poetry. They address his concept of the relationship between God and man.
