| A Persian onager was born this month in Virginia, one of he few onagers to be born in captivity or in Iran, where they are endangered. |
| These carts had heavy solid wheels, and were initially pulled by oxen and onagers. |
| Roman siege engines such as ballistas, scorpions and onagers were not unique. |
| The onagri hurled stones of sixty pounds weight to a maximum distance of two hundred and fifty paces. |
| The square towers were not covered by roofs but by platforms, so as to allow catapults or onagri to be placed upon them. |
