   ஐந்திணை எழுபது · Aintiṇai Eḻupatu — Seventy on the Five Landscapes
   70 akam poems · c. 1st–5th century CE
   Author: Mōcikīraṉār · Patiṉeṇkīḻkaṇakku collection

   Title: ஐந்திணை (aintiṇai) = the five tiṇai; எழுபது (eḻupatu) = seventy.
   Seventy akam love poems across the five classical Tamil landscapes.
   The companion piece to Aintiṇai Aimpatu — where that work gives 10 per tiṇai,
   this gives 14 per tiṇai, allowing deeper exploration of each landscape.

   Visual identity: The same five-landscape grammar as Aintiṇai Aimpatu, but
   more expansive — 70 poems rather than 50. The primary colour shifts to
   deep terracotta/copper to distinguish the two works visually while keeping
   the same tiṇai accent system. The hero mark: five dots arranged in a larger,
   more open pentagon — the same shape but with greater breathing room, reflecting
   the collection's greater depth.
