Whenever an augur reported that Jupiter had sent down thunder and lightning, no comitia (a gathering deemed to represent the entire Roman population) could be held. ex avibus Though auspices were typically bird signs, not all birds in the sky were seen as symbols of the will of the Gods.
Setiap kali seorang augur melaporkan bahwa Jupiter telah mengirimkan guntur dan petir ke bawah, majelis (pertemuan yang dianggap mewakili seluruh penduduk Romawi) tidak bisa diadakan. ex avibus Meskipun auspicium biasanya membaca tanda-tanda burung, tidak semua burung di langit dilihat sebagai simbol kehendak para Dewa.
