Pietro Giacomo Porcelli (1872-1943) was the Italian-born sculptor responsible for many statues in Western Australia, including those of C. Y. O'Connor and Alexander Forrest. A bronze statue of Porcelli by Perth artist Greg James was unveiled in Kings Square, Fremantle, in 1993.
Among the adjacent islands are the Lipari group (Aeolian Islands) and Ustica in the Tyrrhenian sea; the Egadi (Favignana, Marittimo, Levanzo) and the Formiche (Ants) near the western extremity; Pantelleria (the ancient Corcyra) between Malta and Tunisia.
This caused a fresh war, which was ended by the Peace of Caltabellotta (1302), by which Frederick retained the title of King of Trinacria, but only for his life, and paid in return an annual tribute of 3000 ounces of gold to the Holy See.
Contrary to the provisions of the peace, Frederick's son Pietro succeeded (1337) and, after him (1342), his five-year old son Louis, and to him again (1355) his brother Frederick III, then thirteen years of age.
