I have to agree because in all of the tauroctony iconography in Mithraism, Sol Invictus/Helios is always depicted as wearing a crown of seven rays. May be both Helios-Mithras and Jupiter emit seven rays.
"On this account, it appears to me that Plato delivers a twofold generation of the Sun; one indeed, in conjunction with the seven governors of the world, when he fashions the bodies of them, and inserts them in circulations; but the other according to the enkindling of light, through which he imparts to the Sun supermundane power. For it is one thing to generate the bulk of the Sun itself by itself, and another in conjunction with a ruling characteristic, through which the Sun is called the king of every visible nature, and is established analogous to the one fountain of good. For as this fountain, being better than the intelligible essence, illuminates both intellect and the intelligible, thus also the sun being better than a visible nature, illuminate both that which is visible and sight. But if the Sun is beyond a visible essence, it will have a supermundane nature. For the world is visible and tangible, and has a body. Hence, we must survey the Sun in a twofold respect; viz. as one of the seven planets, and as the leader of wholes; and as mundane and supermundane, according to the latter of which he splendidly emits a divine light. For in the same manner as The Good luminously emits truth which deifies the intelligible and intellectual order; as Phanes in Orpheus sends forth intelligible light which fills with intelligence all the intellectual Gods; and as Jupiter enkindles an intellectual and demiurgic light in all the supermundane Gods; thus also the Sun illuminates every thing visible through this undefiled light. The illuminating cause too is always in an order superior to the illuminated natures. For neither is The Good intelligible, nor Phanes intellectual, nor Jupiter supermundane. In consequence of this reasoning therefore, the Sun being supermundane emits the fountains of light. And according to the most mystic doctrines, the wholeness of the Sun is in the supermundane orders; for in them there is a solar world, and a total light, as the Chaldean Oracles assert, and which I am persuaded is true. And thus much concerning these things."
