impious and extravagant opinions. They held, as we are told, that there was but one imam, and they ascribed the qualities of divinity to Ali. Some maintained that there were two natures (the divine and the human) in him, others that the last alone was his. Some again said that this perfect nature of Ali passed by transmigration through his descendants, and would continue so to do till the end of all things; others that the transmission stopped with Mohammed Bakir, the son of Zein-al-Abedeen, who still abode on earth, but unseen, like Khizer, the Guardian of the Well of Life, according to the beautiful eastern legend[13]. Others, still more bold, denied the transmission, and asserted that the divine Ali sat enthroned in the clouds, where the thunder was the voice and the lightning the scourge wherewith he terrified and chastised the wicked. This sect presents the first (though a very early) instance of the introduction into Islam of that mysticism which appears to have had its original birth-place in the dreamy groves of India. As a political party the Ghoollat never seem to have been formidable.

IV. Such, however, was not the case with the Imamee, the most dangerous enemies of the house of Abbas. Agreeing with the Ghoollat in the doctrine of an invisible imam, they maintained that there had been a series of visible imams antecedent to him, who had vanished. One branch of this sect (thence called the Seveners—Sebiïn) closed the series with Ismaïl, the grandson of Mohammed Bakir, the seventh imam, reckoning Ali himself the first. These were also called Ismaïlites, from Ismaïl. The other branch, called Imamites, continued the series from Ismaïl, through his brother Moosa Casim, down to Askeree, the twelfth imam. These were hence called the Twelvers (Esnaashree). They believed that the imam Askeree had vanished in a cavern at Hilla, on the banks of the Euphrates, where he would remain invisible till the end of the world, when he would again appear under the name of the Guide (Mehdee) to lead mankind into the truth. The Imamee, wherever they might stop in the series of the visible imams, saw that, for their political purposes, it was necessary to acknowledge a kind of locum tenentes imams; but, while the Zeidites, who agreed with them in this point, required in these princes the royal virtues of valour, generosity, justice, knowledge, the Imamee declared themselves satisfied if they possessed the saintly ones of the practice of prayer, fasting, and alms-giving. Hence artful and ambitious men could set up any puppet who was said to be descended from the last of the visible imams, and aspire to govern the Mohammedan world in his name.
