Klosterneuburg, on the right bank backed by the Kahlenberg, owes its name to the great Augustine monastery, rebuilt in the seventeenth century, the oldest and wealthiest of the monasteries belonging to this Order in Austria. This Kloster is standing evidence in stone of the truth that great events from small occasions spring, for its establishment on this spot is said to have been the result of a mere puff of wind. In the chronicles of the monks themselves the story of the origin of the place is thus presented: The Margrave, Leopold the Fourth--or Leopold the Holy--having erected a new family fortress, on the summit of Mons Cetius (now the Leopoldsberg), was sitting one evening at the window of his hall, musing on the passing events of his time--on the fate of the old emperor whom he had abandoned--and visited, perhaps, with compunctious feelings as he bethought him of his own sinful course. At his side sat his beloved spouse, the Margravine Agnes; and while they were talking over the religious topics of the day--the endowment of monasteries, the purchase of masses, and the powerful efficacy of good works in quieting the upbraidings of conscience, Leopold expressed an earnest desire to promote the glory of God by raising a sumptuous altar, and surrounding it by holy men, who should there serve Him night and day. But among the number of inviting spots which there met the eye, he could not decide which was the most eligible for the building in contemplation. Thus perplexed in his choice, he appealed to his wife; and just as she leant forward to take a more minute survey of the adjacent country, a gentle breeze, suddenly rising, fluttered for an instant amidst her flowing ringlets, and then, lifting her veil, carried it away--no one knew whither. For some days subsequent to this incident, strict search was made for the veil, but without effect. It could neither be recovered by threats of punishment nor promises of reward.
