Ammianus Marcellinus, Constantius and Gallus 23-25
“And since, as is natural in the world capital, the harsh diseases overpower so intensely that the profession of healing fails at treating them, the plan for safely is that no one will go to see a friend who suffers some disease like this. And some more cautious people add another salubrious remedy to this: slaves who have been sent to ask about the health of someone related to people who have this sickness are not allowed to enter the home before they have cleansed their body with a bath. This is how much they fear a sickness seen by other people.
But even when these practices are rather consistently performed, there are some people who, if they are invited to a wedding where gold might be offered to their open right hands, will run all the way to the Spoletium struggling, even though the strength of their limbs is weak from sickness.
But the mass of the poorest and lowest born people: some of them spend their entire nights in bars while some others haunt the shadows of the theater-awnings which Catullus during his aedileship was the first of all to have suspended as he emulated that Campanian corruption. Some of them play dice violently, sounding out foully when they draw air rapidly into their quivering nostrils; or, that thing they like most of all: they stand with their mouths agape from dawn to dusk in rain or shine analyzing the details of charioteers and the strengths and weaknesses of their horses.
And it is completely a surprise to see an uncountable crowd of plebians with a burning passion in their minds, hanging on what happens in the chariot races. These things and those like them allow nothing serious to happen at Rome.”
Et quoniam apud eos, ut in capite mundi, morborum acerbitates celsius dominantur, ad quos vel sedandos omnis professio medendi torpescit, excogitatum est adminiculum sospitale, nequi amicum perferentem similia videat, additumque est cautioribus paucis remedium aliud satis validum, ut famulos percontatum missos quem ad modum valeant noti hac aegritudine colligati, non ante recipiant domum, quam lavacro purgaverint corpus. Ita etiam alienis oculis visa metuitur Iabes.
Sed tamen haec cum ita tutius observentur, quidam vigore artuum imminuto, rogati ad nuptias, ubi aurum dextris manibus cavatis offertur, impigre vel usque Spoletium pergunt. Haec nobilium sunt instituta.
Ex turba vero imae sortis et paupertinae, in tabernis aliqui pernoctant vinariis, non nulli sub velabris umbraculorum theatralium latent, quae, Campanam imitatus lasciviam, Catulus in aedilitate sua suspendit omnium primus; aut pugnaciter aleis certant, turpi sono fragosis naribus introrsum reducto spiritu concrepantes; aut quod est studiorum omnium maximum ab ortu lucis ad vesperam sole fatiscunt vel pluviis, per minutias aurigarum equorumque praecipua vel delicta scrutantes.
Et est admodum mirum videre plebem innumeram, mentibus ardore quodam infuso, e dimicationum curulium eventu pendentem. Haec similiaque memorabile nihil vel serium agi Romae permittunt. Ergo redeundum ad textum.
