From a specialist collection of militaria, London, UK, collected 1990s onwards. Accompanied by an academic paper by military specialist Dr Raffaele D'Amato, dated 15 July 2019 and titled 'Eastern Roman Empire - Greek Fire Bomb or Hand Grenade (μεσαίον kακάβιον) 9th-11th century AD'.

Apart from the use of siphons or manual flame-throwers called cheirosiphona, special corps of Roman soldiers employed terracotta grenades, in the form of small jars, abundantly evidenced in archaeological excavations. They were called μεσαία kακαβιά or κυτροκακάβια where the former had a bulbous shape and the latter a more cylindrical form.
