Zeus is occasionally conflated with the Hellenic [[sun god]], [[Helios]], who is sometimes either directly referred to as Zeus' eye, or clearly implied as such. [[Hesiod]], for instance, describes Zeus' eye as effectively the sun. This perception is possibly derived from earlier [[Proto-Indo-European religion]], in which the sun is occasionally envisioned as the eye of [[Dyeus|*''Dyḗus Pḥ<sub>a</sub>tḗr'']] (see [[Hvare-khshaeta]]).<ref>{{cite book|last1=West|first1=Martin Litchfield|author-link=Martin Litchfield West|title=Indo-European Poetry and Myth|date=2007|publisher=Oxford University Press|location=Oxford, England|isbn=978-0-19-928075-9|url=http://library.globalchalet.net/Authors/Poetry%20Books%20Collection/Indo-European%20Poetry%20and%20Myth.pdf|access-date=7 May 2017|pages=194–196}}</ref> [[Euripides]] in his now lost tragedy ''Mysians'' described Zeus as "sun-eyed", and Helios is said elsewhere to be "the brilliant eye of Zeus, giver of life".<ref>Cook, p.

Although the connection of Helios to Zeus does not seem to have basis in early Greek cult and writings, nevertheless there are many examples of direct identification in later times.<ref>Cook, pp [https://archive.org/details/zeusstudyinancie01cookuoft/page/186/mode/2up?view=theater 186–187]</ref> The Hellenistic period gave birth to [[Serapis]], a Greco-Egyptian deity conceived as a chthonic avatar of Zeus, whose solar nature is indicated by the sun crown and rays the Greeks depicted him with.<ref name=":co188">Cook, pp [https://archive.org/details/zeusstudyinancie01cookuoft/page/188/mode/2up?view=theater 188–189]</ref> Frequent joint dedications to "Zeus-Serapis-Helios" have been found all over the Mediterranean,<ref name=":co188"/> for example, the Anastasy papyrus (now housed in the [[British Museum]] equates Helios to not just Zeus and [[Serapis]] but also [[Mithras]],<ref>Cook, p.
