Judging by the consideration mentioned first, we should have no difficulty in believing that St. Gregory used neumatic notation in his Antiphonary In ac- cordance with the second view, however, we should feel inclined to put the beginning of neumatic writing about the eighth century. ^

As to the origin of the neums students are now on the whole agreed that they are mainly derived from

ond IS the highest (torculus); and so on. In these combinations the elements generally preserve their original form pretty clearly, except that the angles are often rounded off, as indicated below. When used sing y, the acutus, too, retained its shape fairly accu- rately and from its shape received the name virga (vir- gula). The gravis, however, was generally converted into a short horizontal line (— ),or adot, or some- thing similar, and hence received the name of punc- tum. In this form it is also used in an ascending group of three or more notes (..^, seandicus) and in a
