In the various manuscripts in which are preserved these works, Luchetto's name appears Occitanised as Luchetz, Luqetz, or Luquet and Gateluz or Gatelus.
Luchetto's first diplomatic activity occurred in 1266, when he acted as an ambassador from Genoa to Pope Clement IV and Charles of Anjou.
Luchetto was still acting as Guelph podestà of Bologna on 6 March 1277, when Enzo of Sardinia, son of the Emperor Frederick II and long languishing in a Bolognese prison, dictated his testament in the presence of nobili viro Luchitto de Gatalusiis cive januensi Bonon.
Through his long and varied career Luchetto had acquired interests in property in Sardinia, and he appeared in documents of Nino Visconti, Judge of Gallura, and Ugolino della Gherardesca, capitano del popolo of Pisa.
