Frühhelladikum
Matt-painted pottery, from the Middle Helladic period demonstrates many stylistic motifs that can be traced back to the Early Helladic Period and even other Aegean cultures. Patterns like oblique lines, zigzags, lozenges, running dogs, spiraliforme, and circles and triangles alternating one another beneath the rim on Middle Helladic pottery have been found to be inspired by Cycladic pottery motifs. Spiraliforme can also be traced back to Crete, as well as Griffon motifs. However, patterns like lozenges and pendent-style triangles on matt-painted pottery is a continuation of stylistic motifs from the Early Helladic period, and the addition of vertical fringed lines on pottery is an advancement that took place during the Middle Helladic period itself. With the majority of designs and motifs on Middle Helladic pottery being Cycladic in influence it can be assumed that the Middle Helladic culture and the Cycladic culture interacted with one another heavily.
