Introduction
Sex Sems, also written Seşims and known formally as Melek Semsedin ('the sun of the faith'), is the Yazidi angel of the sun. One of the seven Holy Beings at the centre of the faith, he embodies sunlight, the divine light of God, and the life-giving warmth that sustains the world.
For Yazidis the sun is not merely a star but a sign and channel of the divine, and it is Sex Sems who stands behind it. Yazidis pray toward the sun, swear their most solemn oaths by him, and honour him with a fast each winter. He is among the most beloved and most visible of the Seven Angels.

The Sun of the Faith
Among the seven Holy Beings, Sex Sems is the one most closely tied to the sun. He is the divinity of sunlight, the source of light and life and, in Yazidi understanding, a manifestation of the divine light of God himself. Where the supreme God is hidden and transcendent, the sun is something of him that can be seen and felt each day.
He is also linked with fire, which is regarded as the earthly counterpart of the sun's heavenly light, and with oaths: to swear 'by Sex Sems' is among the most binding promises a Yazidi can make. Light, warmth, truth and life all gather around his name.
Sex Sems Among the Seven Angels
Sex Sems is one of the seven Holy Beings led by Tawuse Melek, the Peacock Angel. His earthly incarnation is remembered as one of the four sons of Ezdina Mir, an early leader of the faith, alongside his brothers Fexredin, Nasirdin and Sejadin. These four are honoured as the ancestors of the Semsani sheikh lineage, one of the great priestly families of Yazidism.
There is a fitting symmetry among the brothers: where Sex Sems is the personification of the sun, his brother Fexredin is the personification of the moon, and is also remembered as a great composer of the sacred hymns. Together they reflect the Yazidi reverence for the lights of heaven.
Sun Veneration in Yazidism
The reverence for Sex Sems shapes Yazidi worship every day. Yazidis pray facing the sun at set times, and the morning prayer in particular is offered toward the rising sun. The first light of dawn is treated as holy, a daily blessing from the divine.
At Lalish, the holiest Yazidi sanctuary, Sex Sems has his own shrine, and the rising sun is said to strike it first among the buildings of the valley. Pilgrims honour him there, and his presence is felt wherever sunlight falls upon the stones.
The Sesims Fast and Worship
Sex Sems is also honoured in fasting and song. Each December Yazidis keep the Rojiyen Seşims, a three-day fast held in his name shortly before the Feast of Ezi. Many personal prayers for help and healing are addressed to him, and he is praised throughout the sacred qewls, the hymns at the heart of Yazidi worship.
Ancient Roots and Parallels
The Yazidi veneration of the sun has long drawn the attention of scholars, who see in Sex Sems echoes of much older sun worship in the region, from the Mesopotamian sun god Shamash to the Iranian divinity Mithra, who was likewise bound up with the sun and with the keeping of oaths. Such parallels point to the deep antiquity of the tradition. As ever, though, they are best read as inheritances woven into a distinct living faith, not as proof that Yazidism is simply an older religion in disguise.
Symbolism
Sex Sems gathers together some of the most universal of all religious symbols. The sun is light against darkness, life against death, and constancy itself, rising faithfully each day. As the divine light of God, he makes the unseen Creator visible in the most ordinary and most magnificent of ways.
His link with oaths binds light to truth: just as the sun reveals all things, so a promise made in his name cannot be hidden or broken. In Sex Sems, the Yazidi sees the warmth of God shining upon the world.
Debates and Misconceptions
Do Yazidis worship the sun? Not as a god in itself. Yazidis are monotheists who revere the sun as a sign and channel of the one God's light, embodied in the angel Sex Sems. Turning toward the sun in prayer honours the Creator through his creation, much as believers in other faiths turn toward a holy place. For the same reason it is wrong to dismiss Yazidis as mere 'fire worshippers'.
Is Sex Sems the same as the poet Shams of Tabriz? No. Although some traditions link holy figures to the angels under many names, the Yazidi Sex Sems is the sun-being of the Heptad, a distinct holy figure, not the historical companion of the poet Rumi, despite the shared word 'shams', meaning sun.
