The tradition of the mortarboard
Traditionally, the mortarboard was symbolically presented at the graduation ceremony, especially when the graduate was receiving their doctorate. From this point on, the graduate was entitled to wear the classic regalia to present himself to the outside world as a scholar. Having consistent official attire primarily served to differentiate academics from courtly society, which often had no access to education, as well as for differentiation among the scholars themselves. The faculties were distinguished from one another by different coloured clothing. This was intended to illustrate the various ranks of the faculties and the prevailing relationship of authority between them.
This tradition has stood the test of time and to this day the graduates of different the faculties wear different coloured tassels, hats or gowns. Ever since this time, it has been customary for lawyers to wear a purple tassel, medical graduates a green tassel and theologians a red tassel on their mortarboards. These days, however, this is only of symbolic importance. Although mortarboards are less commonly worn for the presenting of doctorate degrees these days, they have always been a symbol of the achievement of an academic title, e.g. a bachelor’s or master’s degree.
