Pliny the Elder (1st century CE) states that the port of Tyndis was located at the northwestern border of Keprobotos (Chera dynasty).[25] The North Malabar region, which lies north of the port at Tyndis, was ruled by the kingdom of Ezhimala during Sangam period.[26] According to the Periplus of the Erythraean Sea, a region known as Limyrike began at Naura and Tyndis. However the Ptolemy mentions only Tyndis as the Limyrike's starting point. The region probably ended at Kanyakumari; it thus roughly corresponds to the present-day Malabar Coast.
