Are there ancient writers that mentions halos / nimbus - 1-8 century

Are there ancient writers that mentions halos / nimbus - from 1-8 century? 1. How was the halo adopted in the church? And what is its historicity? 2. I read from some sources that in the beginning it was reserved only for the Lord but in later time it was depicted on saints. 3. Did anyone wrote anything about it? Thanks in advance. ........................................................................... **UPDATE** I found only this - > “Marcus Servius Honoratus, a Roman grammarian of the late 4th century, > in his commentary on Virgil's works defines the Nimbus as a "divine > cloud" ("nimbo effulgens: nube divina, est enim fulgidum lumen quo > deorum capita cinguntur. Sic etiam pingi solet" - Servianorum in > Vergilii Carmina commentariorum / Ed. E. K. Rand. Lancaster, 1946. > Vol. 2. P. 471). The Latin theologian Isidore of Seville in his > Etymologies mentioned the Nimbus as a radiance around the heads of > angels (Isid. Hisp. Etymol. XIX 32. 2).” https://www.pravenc.ru/text/2577657.html Are there maybe church fathers that talk about it or other persons besides from Marcus Servius Honoratus and Isidore of Seville?
