Agesistratus (in Greek: Αγησίστρατος) was a prominent ancient Spartan mathematician and engineer.
[1] Agesistratus particularly focused on military fortifications and the construction of war machines.
He wrote the work "Siege Machines," specifically referring to "greater catapults".
Agesistratus constructed the largest catapult of antiquity, whose effective range of a 1.85 m long javelin reached 4 stades, about 750 m, literally piercing any shield with a breastplate carried behind it.
However, his work is mentioned by his student, also a mathematician and engineer, Athenaeus Mechanicus, as well as by the Roman architect Vitruvius.
