Thanks! Marcomanni were one of the Germanic tribes which inhabited the region around the Danube. Initially they were Rome's enemies, but like so many other barbarian tribes, the Marcomanni were "hired" by Rome to patrol the border of the empire against further invasion by other tribes. This would have during the mid-Fourth to mid-Fifth century A.D.
Good call on the Oregano! I was planning on doing something to represent an autumn scene.
