In this article, we explore the longue durée philosophical background of Mughal Emperor Akbar's sun worship. Although Akbar's sun project may have been triggered by contemporary Hindu and Zoroastrian ideas and practices, we argue that Akbar's Neoplatonic advisers reframed it as a universal cosmotheistic tradition that, at the start of the new millennium, served as the perfect all-inclusive imperial ideology of Akbar's new world order. The astonishing parallels with the much earlier Neoplatonic sun cult of Roman Emperor Julian demonstrate that, although having characteristic of its own, Akbar's sun project was not that unique and should be seen as a fascinating late example of a so-far completely forgotten ancient Neoplatonic legacy of seeing the philosopher king, via the Sun, via illumination, connected to the One.

The Ryukyu (Okinawa) Islands are situated in sub-tropical zone between the Japanese Archipelago and Taiwan. Although Okinawan people have a rich tradition of star lore, few studies have been undertaken on its relevance to subsistence, religion and the socio-political system. This paper is a first attempt to explore a systematic relationship between star lore (e.g. relating to the Pleiades) with agriculture, fishing, navigation and religious practice. This paper also considers the possibility of interpreting the nature of prehistoric and historical stone structures from the viewpoint of archaeoastronomy. This kind of analysis is likely to be fruitful, since the kingship of the Ryukyu Islands was strongly associated with sun worship.
