Rabbi Moses ben Jacob ibn Ezra, known as Ha-Sallaḥ ("writer of penitential prayers") (Arabic: أبو هارون موسى بن يعقوب ابن عزرا, Abu Harun Musa bin Ya'acub ibn Ezra, Hebrew: משה בן יעקב הסלח אבן עזרא,) was a Jewish, Spanish philosopher, linguist, and poet. He was born at Granada about 1055 – 1060, and died after 1138. Ezra is Jewish by religion but is also considered a great influence in the Arabic world in regard to his works. He is considered one of the greatest poets to originate from Spain and was thought of as ahead of his time in terms of theories surrounding the nature of poetry. One of the more revolutionary aspects of Ezra’s poetry that have been debated over is his definition of poetry as metaphor and how it fuses Aristotle’s early ideas. Ezra’s philosophical works were minor compared to his impact on poetry, but they address the relationship that is held between God and man.
