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 (Servius the Grammarian), 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 **The Etymologies of Isidore of Seville (c. 560-636 AD?):** > **The light that is depicted as being around the heads of angels is > called a nimbus,** although a nimbus is also the dense part of a cloud > (nubis). 3.Ahood (capitulum) is commonly called a capitulare.
