Abstract: The ancient city of Tlos is one of the foremost Lycian cities in terms of its tradition of rock-cut tombs. Increasing in number towards the east and north of the city’s necropolis, these tombs can be broken down into four different groups based on the layout of their front facades. While the first group consists of facades resembling homes, those are followed by tombs with a temple-like appearance, latticed facades, and tombs with a simple sarcophagus appearance. Additionally, each group can be further divided into lesser typolo-gical styles. The studies carried out in Tlos’s rock tombs have led to the discovery of much information regarding the cultic practices carried out in the city. The inscriptions found on the front of these tombs shed light on the owner of these tombs and their tenancy. The tombs’ interiors provide us with the chance to understand the city’s burial traditions and details about their beliefs regarding the afterlife. The sepulchral areas directly related to the rock tombs are another interesting find regarding the death cult. These aforementioned areas consist of stele niches, stele sockets, altar areas, and depressions where offerings were placed. General opinion leans towards these arrangements, especially steles and altar areas, being a part of the tombs’ later, secondary periods of use. A stele dated to the Late Archaic- Early Classical Period recovered from the Tlos necropolis indicates that this tradition has been observed since the early ages of these rock tombs.
