This paper contains some of the conclusions resulting from the field surveys conducted between 2018 and 2021 in Octapolis on the road network in Lycia based on the Monumentum Patarense (MP). Some new data and consecutive updates are presented. In the paper, the issues of the political status of Octapolis and the locations of Lyrnai, Hippucome, and the Sanctuary of Loandan Gods are discussed. It is accepted that the use of Octapolis in the MP refers to a region on the western border of Lycia, while sometime after the 2nd c. AD it became the name for a city consisting of a group of communities including those of Lyrnai and Hippucome, as the evidence from epigraphic and literary sources show. Some new unpublished inscriptions found in the field surveys enlighten the ancient geography and some historical periods of the region. The location of Lyrnai is now confirmed as Kayadibi through one of the new inscriptions found on the site. Another new inscription from Kayadibi is a name list and some specific names in the list, such as Agreophon, Agroitas, Agrotheos, Theronides, are found almost entirely only in Caunus and Octapolis, which indicates a demographic affiliation within these communities. The site of Çukurasar has been accepted as the polis centre of Hippucome, which seems to have disappeared already in a period when Octapolis became the name of a city. A new inscription from Çukurasar reads that the city supported Mithradates Eupator VI. It is now clear that Hippucome at Çukurasar was one of the remarkable cities, like Caunus, supporting Pontic forces between 89/8 and 85 BC on the border between Caria and Lycia during the first Mithradatic war. İnhisar, usually accepted as Hippucome, was the place where the Sanctuary of the Loandan Gods was located, within the territory of Hippucome. Additionally, two new imperial honorary inscriptions from İnhisar are published in this paper. One is for Caracalla, erected sometime between 213-217 AD, and the other is for an emperor or an empress probably dating from a period within the 2nd-4th centuries AD. [ABSTRACT FROM AUTHOR]
