In Greek mythology, Ēōs (/ˈiːɒs/; Ionic and Homeric Greek Ἠώς, Attic Ἕως Éōs, "dawn", pronounced [ɛːɔ̌ːs] or [héɔːs]; Aeolic Αὔως Aúōs, Doric Ἀώς Āṓs) is a Titaness and the goddess of the dawn, who rose each morning from her home at the edge of the Oceanus.
Eos had a brother and a sister, Helios, god of the sun, and Selene, goddess of the moon.
Eos is cognate to Vedic Sanskrit Ushas and Latin Aurora, both goddesses of dawn, and all three considered derivatives of a PIE stem *h₂ewsṓs (later *Ausṓs), "dawn", a stem that also gave rise to Proto-Germanic *Austrō, Old Germanic *Ōstara and Old English Ēostre/Ēastre. This agreement leads to the reconstruction of a Proto-Indo-European dawn goddess.
The dawn goddess Eos was almost always described with rosy fingers (ῥοδοδάκτυλος, rhododáktylos) or rosy forearms (ῥοδόπηχυς, rhodópēkhys) as she opened the gates of heaven for the Sun to rise. In Homer, her saffron-coloured robe is embroidered or woven with flowers; rosy-fingered and with golden arms, she is pictured on Attic vases as a beautiful woman, crowned with a tiara or diadem and with the large white-feathered wings of a bird.
Eos is the goddess of the dawn in Greek mythology. It may also refer to Aeos, one of the four horses that drew the chariot of the young God Helios in Greek mythology.
Eos or EOS may also refer to:
Eos (also called EosFP) is a photoactivatable fluorescent protein (PAFP).
Eos was isolated from the coral Lobophyllia hemprichii in a large-scale screen for PAFPs.
Eos undergoes an irreversible photoconversion in response to 390 nm light. Prior to this conversion, it exhibits a green emission peak at 516 nm. Following conversion, it has a red emission peak at 581 nm.
Wild-type Eos is a tetrameric protein. It has been modified to generate a monomeric form (referred to as mEos) that is more amenable for experiments involving labeling of a single molecule. Further improvements of mEos lead to mEos2 that is able to mature at 37 °C and can be used in mammalian cells. One drawback of mEos2 - the formation of oligomers at high concentrations - was resolved in the next generation of mEos: mEos3.1 & mEos3.2.
Like other PAFPs, Eos can be used to optically label single cells for subsequent analysis. Because Eos is available in monomeric forms, it can also be used to observe the kinetics and trafficking of single molecules as a fusion protein.
It was more than a matter of knowin'
Or the words that were finally said
It was more than the comin' or goin'
Or the things that were made in your head
It was more than a matter of wantin'
And needin' the foolish things I gave
As if I ever cared to make you cry
Could've been right to know that it wasn't
Yet you knew I was sorry
I dared to make you cry
As if I would
As if I could
As if I tried
But the words that were finally spoken
Like the thoughts that remain in my soul
And hearts that were finally broken
And embrace that never be hold
And the words that I never told you
But I told you, the foolish things I said
As if I ever cared to make you cry
I could've been right to know that I wasn't
Yet you knew that I was sorry
I dared to make you cry
As if I would
As if I could
As if I tried
As if I ever cared to make you cry
I could've been right to know that I wasn't
Yet you knew that I was sorry
I dared to make you cry
Could have been strong but the words didn't rhyme
