He became a learned man, and lectured at Paris. That he was possessed with no small opinion of his talents would appear from the legend told of him as well as of St. Augustine. He had announced that on a certain day in a single lecture he would set forth the complete doctrine of the mystery of the most Holy Trinity. The afternoon before the day appointed, he walked by the river, thinking how he should arrange his subject so as to include it all. He chanced upon a child who was dipping up the river water with a snail shell and dropping it into a little trench. Smiling, he asked what should be the object of this; and the child told him that he was putting the whole river into his trench. As the great scholar was explaining that this could not be done, he suddenly felt himself chidden and taught--how much less might he perform what he had set for the next morning. He stood speechless at his presumption, and burst into tears. The next day ascending the platform he said to the crowd of auditors, “Let it suffice you to have seen Alanus”;[128] and with that he left them all astonished, and himself hastily set out for Citeaux. On arrival he asked to be admitted as a _conversus_, and was given charge of the monastery’s sheep. Patient and unknown, he long plied this humble vocation. But at length it chanced that the abbot took him to a council at Rome, in the capacity of hostler. And there he beat down the arrogance of a heretic with such arguments that the latter cried out that he was disputing either with the devil or Alanus, and would say no more. Such is one story. By another he is made to seek the monastery of Clairvaux, and there become a monk under St. Bernard. It is also written that he became an abbot, and then a bishop, but afterwards resigned his bishopric. However all this may have been, he died and was buried, and was subjected to many epitaphs. On what purports to be an old copy of his tomb at Citeaux, he is shown with St. Bernard, and called Alanus Magnus. The title _Doctor universalis_ has always clung to his memory, which will not altogether fade. For if Adam of Saint-Victor was the greatest of Latin mediaeval hymn-writers, Alanus has good claim to be called the greatest of mediaeval Latin poets in the field of didactic and narrative poetry.[129]
