Trom

1. Artillery piece, cannon, small cannon.

2. There is evidence, including in Fernão Lopes's chronicles, that gunpowder was used in Portugal and other kingdoms in the Iberian Peninsula. Beside references to 'trons' or 'trõos' as military equipment, there is an interesting sarcastic remark made by Queen Leonor Teles about the Master of Avis, the future King João I, and his involvement in the 1383 uprising in Lisbon. She says that she does not know whether the Master of Avis is "a master of cannons [trõos] or of bombards" (sse he meestre de troos sse de bombardas). [João1, ch.30]
