The 4th-century-BC sanctuary of Labraynda in south-western Asia Minor was seemingly created in one single short building project. Thanks to dedicatory inscriptions, we know that seven of the most important buildings were erected either by Maussollos, who died in 352, or by his younger brother Idrieus, who died 8 years later, in 344 BC. It is suggested that there were rather two separate building projects, one by Maussollos and the other one by Idrieus. The two brothers may have used their roles as patrons of the Carian sanctuary in two different ways; this could be explained as two different approaches to the display of power. Maussollos appears to have used the building project at Labraynda as a display of power primarily to an international audience. What we hear about him in ancient written sources shows him to have been a very ambitious man with farreaching plans. That his audience was international, and not only greek, is also clearly indicated by the erection of the Mausoleum at Halikarnassos. The impact of that monument was world-wide. Idrieus, who took over in 351 after an interregnum of some two years with Artemisia as the ruler, gives no impression of having had an international audience in mind. His activity seems to have been directed primarily towards the Carians. The change that took place when Idrieus succeeded Maussollos seems thus to have been a change from expansion to consolidation.
