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.
