Faros, jedan od najstarijih gradova na istočnoj obali Jadrana, osnovali su Parani 385./4. godine pr. Kr. na mjestu Staroga Grada na otoku Hvaru. Usprkos znatnom otporu ilirske autohtone sredine prilikom osnivanja grada, utemeljena je grčka kolonija Faros uz podršku i pomoć Dionizija Sirakuškog. S obzirom na to da su Parani bili skloni pitagorejskoj filozofiji, čija su načela primijenjena u planiranju grčkih gradova, i da je posredstvom pitagorejaca uspostavljen kontakt Parana s Dionizijem Starijim, neophodno je u tom smislu promatrati planiranje urbanog prostora Farosa. Poznato je da je Hippodam bio pitagorejac te da je uveo pitagorejsku teoriju brojeva u urbanizam. To se može vidjeti prvenstveno iz analize planova gradova ustrojenih prema pitagorejsko¬hipodamskim principima (Milet, Pirej). Karakterističan pitagorejski sistem planiranja grada, prilagođen poznatoj shemi tetraktys, može se raspoznati u bolje istraženim arheološkim lokalitetima (Priena). Arheološkim istraživanjima Farosa otkrivena je njegova urbana struktura. U koncepciji farskih stambenih blokova otkrivenih u jugoistočnom dijelu grada opaža se primjena pitagorejskih numeričkih principa. Grad je bio ustrojen prema pitagorejskim numeričkim postavkama važnim za ostvarenje sistema harmonije. Raščlanjenjem urbanog tkiva pravokutnicima parcela i insula, su Farosu je postignut sklad temeljen na načelima proporcija i brojeva, tipičan za grčki urbanizam. ; Pharos, one of the oldest cities on the eastern coast of the Adriatic, was founded by Parians in 385/4 BC on the site of Stari Grad on the island of Hvar. In spite of the considerable resistance of the Illyrian indigenous people while the city was being founded, the Greek colony was nevertheless established, with the support and assistance of Dionysius of Syracuse. Since the Parians were inclined to Pythagorean philosophy, and since the contact was probably made with Dionysius the Elder via the Pythagoreans, it is essential to look at the planning of the urban space of Pharos in this light. It is known that Hippodamus was Pythagorean and that he introduced Pythagorean number theory into the town planning. This can be seen primarily from an analysis of the plans of the cities organised according to the Pythagorean–Hippodamian principles (Miletus, Piraeus). The characteristically Pythagorean system of town planning, well¬-adjusted to the tetractys diagram, can be recognised in a rather well explored archaeological sites (Priene). Recent archaeological research in Pharos discovered how urban structure is articulated. The application of numerical principles can be observed in how Pharian residential blocks were conceptualized, revealed in the south¬east part of the city. The city, organised according to Pythagorean numerical, became important for accomplishing harmonious system. By construing the urban texture on the basis of the rectangular plots and insula, the harmony based on the principle of proportion and numbers – typical of Greek urban planning and design – was achieved in Pharos
