Also known as Asselino, Anselmo. Dominican from Lombardy; papal envoy to the Tartars. His antecedents and the dates of his birth and death are not known. In 1245 he headed one of four missions that Innocent IV sent by different routes to the Tartars, who were exhorted to cease their depredations and become Christians. Apparently, he was also commissioned to treat with the dissidents and Moslem sultans of the Near East with regard to reunion and conversion. These tasks occupied him and his Dominican staff of four until the fall of 1246. Going from Acre, the friars contacted the Tartar general Batschu in the Transcaucasus (or middle Persia) on May 24, 1247, 59 days after leaving Tiflis. Ascellino's undiplomatic refusal to follow Oriental protocol endangered the lives of the envoys and led to great discomfort, hunger, and insults. Finally Batschu accepted the papal letters but forced Ascellino to await a reply from the Grand Khan. He departed for Europe on July 25, 1247, accompanied by two Tartar envoys to the pope. The letters from the khan and Batschu were arrogant, demanding papal submission to the Tartars. Ascellino reached Lyons in the autumn of 1248. His later career is unknown. The story of his martyrdom in Asia is pure speculation.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
