(b Varignana, c. 1460–70; d Bologna, 12 May 1539). Italian sculptor and architect. He was the son of Giovanni da Varignana and is mentioned in a contemporary poem as a pupil of Andrea Sansovino. According to Vasari, after the discovery in 1506 of the Laokoon (1st century AD; Rome, Vatican, Mus. Pio-Clementino), Aimo participated in a contest arranged by Bramante to make the best copy in wax of the ancient marble statue for later casting in bronze. His fellow competitors were Zaccaria Zacchi, Alonso Berruguete and Jacopo Sansovino. Raphael, who had been appointed as judge, decided in favour of Sansovino.
