Purported Polish nobleman

Abraham ben Abraham (, lit. "Avraham the son of Avraham") (c. 1700 – 23 May 1749), also known as Count Valentine (Valentin, Walentyn) Potocki (Pototzki or Pototski), was a purported Polish nobleman (szlachta) of the Potocki family who converted to Judaism and was burned at the stake by the Roman Catholic Church because he had renounced Catholicism and had become an observant Jew. According to Jewish oral traditions, he was known to the revered Talmudic sage, the Vilna Gaon (Rabbi Elijah Ben Shlomo Zalman [1720–1797]), and his ashes were interred in the relocated grave of the Vilna Gaon in Vilna's new Jewish cemetery. Although the Orthodox Jewish community accepts the teachings about Abraham ben Abraham, including the involvement of the Vilna Gaon,
secular scholars have until recently concluded that it is a legend.

Polish author Józef Ignacy Kraszewski, based on the story written in Hebrew from 1766 by Judah Hurwitz, Ammudei Beit Yehuda in Amsterdam relates that young Potocki and his friend Zaremba, who traveled from Poland to study in a seminary in Paris, became interested in an old Jew whom they found poring over a large volume when they entered his wine shop. This Jew might have been their own countryman, Menahem Man ben Aryeh Löb of Visun, who was tortured and executed in Vilna at the age of seventy (3 July 1749). Tradition has brought this Jewish martyr into close connection with the Ger Tzedek, but fear of the censor has prevented writers in Russia from saying anything explicit on the subject. His teachings and explanations of the Old Testament, to which they, as Roman Catholics, were total strangers, so impressed them that they prevailed upon him to instruct them in the Hebrew language. In six months they acquired proficiency in the Biblical language and a strong inclination toward Judaism. They resolved to go to Amsterdam, which was one of the few places in Europe at that time where a Christian could openly embrace Judaism. But Potocki first went to Rome, whence, after convincing himself that he could no longer remain a Catholic, he went to Amsterdam and took upon himself the covenant of Abraham, assuming the name of Avraham ben Avraham ("Abraham the son of Abraham"; "the son of Abraham" is the traditional styling of a convert to Judaism, as Abraham was the first who converted to Judaism from polytheism). Potocki's parents got word of his leave from the seminary in Paris and the rumors that he had converted to Judaism and began searching for him. Potocki then fled from France and hid in a synagogue in Vilna, wearing a long beard and peyot like the Perushim (devout Jews who separated themselves from the community to learn and pray). When the Vilna Gaon heard of his whereabouts, he advised him to hide instead in the small town of Ilye (Vilna Governorate). There a Jewish tailor who sewed uniforms for Polish bureaucrats overheard some clients talking about the fugitive divinity student and suspected that the stranger in the synagogue might be he. Later this tailor's son, who liked to disturb the men studying in the synagogue, was sharply rebuked by Potocki; some say Potocki grabbed the boy by the ear and pulled him out the door. The tailor reported him to the Bishop of Vilna, and Potocki was arrested. Potocki walked proudly to the execution site, singing a song that was later sung in the Volozhin yeshiva and that was also sung by Rabbi Isser Zalman Meltzer after Yom Kippur.

Many secondary sources – encyclopaedias of Jewish culture, history and religion – include an entry on Potocki, a Polish magnate and member of the powerful Potocki family, who converted to Orthodox Judaism in 18th century Netherlands and who, after his return to Vilna, was tried by an Inquisition court which sentenced him to burning at the stake. Historians (ex. Janusz Tazbir, Jacek Moskwa,) who have studied the story of Potocki, however, believe it to be invented,Unreliable source: date=September 2020

Tazbir stated that the tragic fate of Potocki, passed through Jewish oral tradition, remains unconfirmed by 18th century Polish or Jewish primary sources and that there is no evidence in any archives or genealogy tree that Potocki existed.

Some have suggested that the Potocki legend is an embellishment of a different story. A report published in the July 1753 edition of The London Magazine describes the story of a very similar execution. The correspondent dated his report 11 June, two days after the end of the Shavuot holiday. It describes "an apostate named Raphael Sentimany, a native of Croatia", who converted to Judaism at the age of 12 and adopted the name Abraham Isacowicz. The report describes his imprisonment and execution in Wilno as the Potocki legend describes. The report also states that he was executed on 9 June, which was the second day of Shavuot, just as in the Potocki story. The only important differences between the Sentimany execution and the Potocki legend are that the martyr's Jewish surname was Isacowicz, called Rafael Sentimany rather than Valenty Potocki, was killed in 1753 rather than 1749, and that he was a Croatian immigrant rather than a Polish noble. Raphael Sentimany is also mentioned in the anonymous British work "Admonitions from the Dead, in Epistles to the Living", published in 1754, in a manner suggestive of the wide exposure of the original report of Abraham ben Abraham's execution.
