[2] He was admired and respected by many scholars of his time, and he began to bring his teachings to Terlizzi, in order to revitalize the academy established by Ferrante de Gemmis.
At the age of 21, he started a correspondence with Antonio Genovesi whose answers are published in his Libro delle lettere familiari.
De Gemmis was also very happy with his idea of reorganizing the professorships; after the publication of his first essay on law in which he defended the rights of Altamura Cathedral against the claims of the bishop of Gravina, Bisceglia obtained many offers of promotion to be a bishop, but he refused in order to continue his research on botany, publishing, in collaboration with famous botanist Vincenzo Petagna, a Memory on the causes of tetanus (Italian: Alla scoperta delle cause che procurano il tetano) and he also wrote about philosophy, economics, botany and agriculture, as well as two short essays about local history, even going back to prehistory.
[2] As mentioned above, he also wrote a work about law, showing that he was also a talented jurist and historian, in the age-old dispute with the bishop of Gravina on the privileges of Altamura Cathedral and his "royal patronage", which means his being subject only to the king.
In fact, he demonstrated that the privileges and tax exemptions enjoyed by Altamura Cathedral were legally right and encompassed by the law of the kingdom.
