Isa - you asked for a writing about icons. Here is a writing
Tertullian ca. 160-225
"Likewise, when forbidding the similitude to be made of all things which are in heaven, and in earth, and in the waters, He declared also the reasons, as being prohibitory of all material exhibition of a latent idolatry. For He adds: "You shall not bow down to them, nor serve them."
So writings existed post 150A.D. and I don't have an exact date of when Tertullian wrote it.
"But in the case of God, whose spirit and influence are diffused everywhere, and can never be absent, it is plain that an image is always superfluous. But they fear lest their religion should be altogether vain and empty if they should see nothing present which they may adore, and therefore they set up images; and since these are representations of the dead, they resemble the dead, for they are entirely destitute of perception. But the image of the ever-living God ought to be living and endued with perception. But if it received this name from resemblance, how can it be supposed that these images resemble God, which have neither perception nor motion? Therefore the image of God is not that which is fashioned by the fingers of men out of stone, or bronze, or other material, but man himself, since he has both perception and motion, and performs many and great actions. Nor do the foolish men understand, that if images could exercise perception and motion, they would of their own accord adore men, by whom they have been adorned and embellished, since they would be either rough and unpolished stone, or rude and unshapen wood, had they not been fashioned by man.
Man, therefore, is to be regarded as the parent of these images; for they were produced by his instrumentality, and through him they first had shape, figure, and beauty. Therefore he who made them is superior to the objects which were made. And yet no one looks up to the Maker Himself, or reverences Him: he fears the things which he has made, as though there could be more power in the work than in the workman."
ALSO: According to the book "Praying with icons" by Jim Forest on page 8 he states that Eusebius and Clement of Alexandria (both who lived in those years you assigned) were against iconography.
Anyway, your assignment wasn't "who was against" or "who they were", it was merely to find writings about iconography in those years.
There ya go.
