Connections with the north fall into two classes, particular points of contact, such as the occurrence on North Greek sites of sherds or vases almost, if not quite, identical in shape or technique with specimens from further north, and general points of similarity between certain northern cultures and the early finds from Thessaly, which are thereby differentiated from contemporary remains in the Aegean area.

It is convenient to take the particular points of contact first. Four monochrome vase lids (Г3λ) from Dhimini are compared by Tsundas to somewhat similar types from Troy I. A fifth has since been found in Tsani IV. The similarity in shape may be admitted, but since this type also occurs in Troy II–V, and the fabric differs, Tsundas' chronological inference is not valid.

In the relief ornamentation, which is not uncommon in the Г3 wares, Tsundas again sees connections with Troy, and this theory is considerably strengthened by the more recent evidence from Rakhmani, where spirals in relief are found in close connection with the horn-shaped lugs. The connection however is slight and consists only in similarity of decoration, for in all other respects the Trojan vases are unlike the Thessalian. Similar plastic ornamentation, including spirals, has been found in Macedonia and it may prove a connecting link between North Greece and Troy. There is however no evidence as yet for the shapes of these Macedonian vases.
