In 1766 he entered the Imperial Academy of Arts, where in 1771 for drawing from nature was awarded a second silver medal. In 1777, for the program "the Sacrifice of Abraham," he received a second gold, and in 1778, too, for the program "the Curse of ham Noah" — the first gold medal with the right to travel abroad, at government expense, for four years. At release he delivered a public speech in the French language. Mentioned paintings showed remarkable talent of the artist and forced to lay great hopes on him, which, unfortunately, did not materialize. Arriving in Paris in 1779, he became interested in there card game and other entertainment and almost did not make art. For all of its foreign pensionerstva he wrote only one painting "the Education of Cupid by mercury" and a family portrait "is the Name of the Marquis de Votes, Admiral of the fleet". Fearing the consequences of such a pastime, he did not dare at the end of the pensioner's life to return to Russia and remained in Paris, although he was sent the money to return home. After he completely abandoned the arts, which appears to have never loved, and information about it reached Russia only twice: in 1811 he was sent by the Russian Ambassador, Prince A. B. Kurakin, to the Minister of education, count A. K. Razumovsky, his manuscript: "Maximes generales pour juger les peintres, leurs ouvrages et le degres auquel ils sont parvenus," for her dedication to the Emperor and to the publication at public expense. But the Council of the Academy, which was instructed to examine it, found that it is a mere extract from the works of Raphael Mengs, published in 1787, "why is the Council, — was stated in the report, was surprised to notice that G. Piskorski ventured in his letter to the Emperor to say about this essay is that it dares to devote to his Majesty this weak experience of your labors within 30 years, when all this work is a glorious essay of Mengs, with whom he only occasionally rearranged the words, and then to their disadvantage". Second, he heard a rumor when N. I. Utkin, subsequently our famous graver, came to Paris as a pensioner. Then Piskorski, having become acquainted with him as a compatriot, and tried to drag him into the card game. In addition to these works, there is also engraved them when he was in the Academy landscape with the caption "gr. vospit. 3rd ASC. IV. Piskorski". (Cumans)
