The predominant, but not exclusive, characteristic of Jewish poetry is its religious strain. Great thinkers, men equipped with philosophic training, and at the same time endowed with poetic gifts, have contributed to the huge volume of synagogue poetry, whose subjects are praise of the Lord and regret for Zion. The sorrow for our lost fatherland has never taken on more glowing colors, never been expressed in fuller tones than in this poetry. As ancient Hebrew poetry flowed in the two streams of prophecy and psalmody, so the Jewish poetry of the middle ages was divided into _Piut_ and _Selicha_. Songs of hope and despair, cries of revenge, exhortations to peace among men, elegies on every single persecution, and laments for Zion, follow each other in kaleidoscopic succession. Unfortunately, there never was lack of historic matter for this poetry to elaborate. To furnish that was the well-accomplished task of rulers and priests in the middle ages, alike "in the realm of the Islamic king of kings and in that of the apostolic servant of servants." So fate made this poetry classical and eminently national. Those characteristics which, in general literature, earn for a work the description "Homeric," in Jewish literature make a liturgical poem "Kaliric," so called from the poet Eliezer Kalir, the subject of many mythical tales, and the first of a long line of poets, Spanish, French, and German, extending to the sixteenth or seventeenth century. The literary history of this epoch has been written by Leopold Zunz with warmth of feeling and stupendous learning. He closes his work with the hope that mankind, at some future day, will adopt Israel's religious poetry as its own, transforming the elegiac _Selicha_ into a joyous psalm of universal peace and good-will. Side by side with religious flourishes secular poetry, clothing itself in rhyme and metre, adopting every current form of poesy, and treating of every appropriate subject. Its first votary was Solomon Gabirol, that "Human nightingale that warbled Forth her songs of tender love, In the darkness of the sombre, Gothic mediæval night. She, that nightingale, sang only, Sobbing forth her adoration, To her Lord, her God, in heaven, Whom her songs of praise extolled."[7] Solomon Gabirol may be said to have been the first poet thrilled by _Weltschmerz_. "He produced hymns and songs, penitential prayers, psalms, and threnodies, filled with hope and longing for a blessed future. They are marked throughout by austere earnestness, brushing away, in its rigor, the color and bloom of life; but side by side with it, surging forth from the deepest recesses of a human soul, is humble adoration of God."
