Modern Redaction
In Apicius, as is common in Roman cookery the term 'bulbos' really does refer to bulbs and these could be the bulbs of tulip, narcissus, and daffodil. These are the 'bulbs' that seem to be referred to by Apicius. . Columella and Pliny the Elder reported that the buds or shoots of reeds were sometime called “bulbs" and sometimes “eyes." Platina included the squill (scilla) and sea onion in the term. Apart from the onion, the other bulbs in these lists contain contain toxic glycosides and CAN BE LETHAL. Only ever use onions in these recipes, DO NOT try the other bulb types. To keep with the 'bulbos' description use small or pickling onions.
In a bowl, combine the shredded onions, olive oil, vinegar and liquamen. Cover and set aside to marinate for 60 minutes. When ready to serve, place in a small bowl and scatter over the cumin.
