Grass Crown
The Corona obsidionalis or graminea ( " siege crown ", " gräserne Crown") was a military award in the Roman Empire. It was awarded to the generals, who succeeded in freeing his beleaguered army. She was made of grass bundles and flowers that were picked where the army was trapped. For the first time it is mentioned in Polybius. Pliny the Elder knew only eight people who had received this award, namely, the tribune of 454 BC Lucius Siccius dentate, Publius Decius Mus, who received the same two armies, Quintus Fabius Maximus Verrucosus, Marcus Calpurnius Flamma, Scipio Aemilianus Africanus, Gnaeus Petreius Atinas, a centurion in the war against the Cimbri, Sulla and Quintus Sertorius. Therefore, it was considered a special honor and as the highest honor of the Crown.
Although it was usually awarded by the army, Augustus received it by the Senate.
