The earthenware vessels usually have rounded bottoms. The earliest ornamentation consists of finger-imprints.
The ornamentation of the period is as a rule confined to spirals, bosses and concentric circles.
The kings of arms in England, Scotland and Ireland wear crowns, the ornamentation of which round the upper rim of the circlet is composed of a row of acanthus or oak leaves.
Dentil mouldings, of which examples may still be seen in the remains of the palace of Blachernae at Constantinople, are characteristic of Venetian ornamentation at this period, and remain a permanent feature in Venetian architecture down to the 11th century.
The invention of colourless Bohemian glass brought in its train the practice of cutting glass, a method of ornamentation for which Venetian glass, from its thinness, was ill adapted.
The ornamentation is of the conventionalized plant type: gold is freely used, and enamel, of a kind different from the Roman enamel used later in Germany, is applied to weapons and ornaments.
Papuan weapons are the bow and arrow (in the Fly River region, the north and north-east coasts); a beheading knife of a sharp segment of bamboo; a shafted stone club - rayed, disk shaped or ball-headed (in use all over the island); spears of various forms, pointed and barbed; the spear-thrower (on the Finsch coast); and hardwood clubs and shields, widely differing in pattern and ornamentation with the district of their manufacture.
They include some of the most brilliantly coloured of all antelopes; the ornamentation taking the form of vertical white lines and rows of spots.
The ornamentation throughout is beautiful, and the west front especially notable.
Others were afterwards supplied by Benozzo Gozzoli and men of lesser note, and the labour of ornamentation was only discontinued in 1464.
