Palike was an ancient city on Sicily. Its archeological site is located in Rocchicella on a spur of basalt in the valley of the Margi river. There are no certain origins to this ancient town. Diodorus Siculus writes that it was founded in 453 BCE by the native Sikel leader Ducetius. It was named after the sanctuary of the Palici nearby. The city was surrounded by strong walls and grew rapidly because of the fertility of its soil. However, it was soon destroyed and the site remained uninhabited at the time Diodorus wrote the Bibliotheca historica, which he finished in approximately 60 BCE.
Palike's destruction most likely happened in 440 BCE, when the city of Trinakie was destroyed by Syracuse according to Diodorus Siculus. Ducetius had died of an illness earlier in the same year. Peter Green and several other historians argue that Trinakie was most likely the same city as Palike. The table of contents of the Bibliotheca historica refers to the Syracusan campaign as being conducted 'against the Picenians', which makes no sense. If the spelling of the Ancient Greek text is slightly altered, this would read 'against the men of Palici'. Trinakie is an ancient indigenous name for Sicily, which would have been a suitable name for the nationalistic ambitions of the Sicels. The city might have been renamed to Trinakie or it could have been the name of its acropolis.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
