It was in 1260, when Mechthild of Magdeburg was at the height of her activity, that Meister Eckhart, next to Plotinus the greatest philosopher-mystic, was born at Hocheim in Thuringia. It seems that his family was in a good position, but nothing is known of his early years. He entered the Dominican Order as a youth, perhaps at sixteen, the earliest age at which novices were admitted into that Order. The course of instruction among the Dominicans was as follows:--After two years, during which the novice laid the foundations of a good general education, he devoted the next two years to grammar, rhetoric, and dialectic, and then the same amount of time to what was called the Quadrivium, which consisted of "arithmetic, mathematics, astronomy, and music." Theology, the queen of the sciences, occupied three years; and at the end of the course, at the age of twenty-five, the brothers were ordained priests. We find Eckhart, towards the end of the century, Prior of Erfurt and Vicar of Thuringia, then Lector Biblicus at Paris, then Provincial Prior of Saxony. In 1307 the master of the Order appointed him Vicar-General for Bohemia, and in 1311 he returned to Paris. We find him next preaching busily at Strassburg,[4] and after a few more years, at Cologne, where the persecution of the Brethren of the Free Spirit was just then at its height. At Strassburg there were no less than seven convents of Dominican nuns, for since 1267 the Order had resumed the supervision of female convents, which it had renounced a short time after its foundation. Many of Eckhart's discourses were addressed to these congregations of devout women, who indeed were to a large extent the backbone of the mystical movement, and it is impossible not to see that the devotional treatises of the school are strongly coloured by feminine sentiment. A curious poem, written by a Dominican nun of this period, celebrates the merits of three preachers, the third of whom is a Master Eckhart, "who speaks to us about Nothingness. He who understands him not, in him has never shone the light divine." These nuns seem to have been fed with the strong meat of Eckhart's mystical philosophy; in the more popular sermons he tried to be intelligible to all. It was not very long after he took up his residence at Cologne that he was himself attacked for heresy. In 1327 he read before his own Order a retractation of "any errors which might be found" (si quid errorum repertum fuerit) in his writings, but withdrew nothing that he had actually said, and protested that he believed himself to be orthodox. He died a few months later, and it was not till 1329 that a Papal bull was issued, enumerating seventeen heretical and eleven objectionable doctrines in his writings.
