Even after the removal of the edicts the old prejudices remained, and the missionaries were regarded as political emissaries, the forerunners of military aggression.
Contrariwise, the sophists were always and essentially professors of the higher education; and, although in process of time specialization assimilated sophistry to the arts, at the outset at any rate, its declared aim - the cultivation of the civic character - sufficiently distinguished sophistical education both from professional instruction and from artistic training: It is true too that in some of the colonies philosophy had busied itself with higher education; but here again the forerunners of the sophists are easily distinguished from the sophists, since the sophists condemned not only the scientific speculations of their predecessors, but also their philosophical aims, and offered to the Greek world a new employment for leisure, a new intellectual ambition.
The Carboniferous forerunners of the tiny club-moss were then great trees with dichotomously branching stems and crowded linear leaves, such as Lepidodendron (with its fruit cone called Lepidostrobus), Halonia, Lepidophloios and Sigillaria, the largest plants of the period, with trunks sometimes 5 ft.
There is considerable reason for believing that the Ceratiocaridae, which are found from the Cambrian onwards, were allied to the existing Nebalia, and may possibly include the forerunners of the true Malacostraca, but nothing is definitely known of their appendages.
The Upper Oligocene Cricetodon in Europe and Eumys in America are the earliest known forerunners of the cricetine Muridae; while at the same time primitive beavers appear in the form of Steneofiber, to be succeeded in the European Pleistocene by the gigantic Trogontherium.
Oxford infected St Andrews, and we find traces of more than one vigorous search made for Lollards among the teaching staff of the Scottish university, while the Lollards of Kyle in Ayrshire were claimed by Knox as the forerunners of the Scotch Reformation.
Now it is true that before 447 B.C., besides the teachers of writing, gymnastics and music, to whom the young Greek resorted for elementary instruction, there were artists and artisans who not only practised their crafts, but also communicated them to apprentices and pupils, and that accordingly the Platonic Protagoras recognizes in the gymnast Iccus, the physician Herodicus, and the musicians Agathocles and Pythoclides, forerunners of the sophists.
Their zeal for renunciation often extended not to pleasures, marriage and property alone, but to cleanliness, knowledge and good manners as well, and in this respect also they were the forerunners of later monks.
The upper Eocene has yielded many birds, most of which are at least close forerunners of recent genera, the differentiation into the leading orders and families being already well marked, e.g.
Of the tribes which occupy the mountains of Siam some are the remnants of the very ancient inhabitants of the country, probably of the Mohn-Khmer family, who were supplanted by a later influx of more civilized Khmers from the south-east, the forerunners and part-ancestors of the Siamese, and were still farther thrust into the remoter hills when the Lao-Tai descended from the north.
