(4) Commerce was practised to some extent in very early times, as is proved by the distribution of Melian obsidian over all the Aegean area and by the Nilotic influence on early Minoan art.
He goes so far as to pronounce the latter to be Cretan importations, their fabric and forms being unlike anything Nilotic. If that be so, the period at which stone implements were beginning to be superseded by bronze in Crete must be dated before 4000 B.C. But it will be remembered that below all Evans's "Minoan" strata lies the immensely thick Neolithic deposit.
To this wave were owed in all probability the Nilotic scenes depicted on the Mycenae daggers, on frescoes of Hagia Triada and Cnossus, on pottery of Zakro, on the shell-relief of Phaestus, &c.; and also many forms and fabrics, e.g.
After Egypt proper was overrun by the " dynastic Egyptian " people of " Armenoid " stock, who came from Asia and founded the kingdoms of Lower and Upper Egypt, the old barbarous Nilotic culture continued to exist in Nubia.
Elliot Smith has shown 7 the existence of the two racial stocks in Egypt, the predynastic Nilotic and the invading "Armenoid " from Asia, the man of higher cranial capacity to whom the blossoming of the Egyptian civilization and art out of primitive African barbarism is to be ascribed.
