The Triumphs of Sulla
196-204 CE
The East ignited with the flame of war. The might of Rome, alongside its client Osroene, bore down upon the combined forces of Persia, Armenia, Atropatene, and Kartlia - all of whom answered to Arsacid kings [1]. Rome had the initiative in these military operations, taking full advantage of its surprised enemy. Armenia fell first, Sulla showing clemency to all but its royal family and fomenting desertion by the Armenian troops remaining with the Persian armies. Kartlia suffered similar subjugation, leaving Persia with only its smallest vassals against Rome.
In conscious imitation of Trajan, Sulla overran Adiabene in his march to the capital, capturing the city of Assur (among others) and burning the supposedly impossible to capture fort of Atra to the ground - true to its reputation. Reaching Ctesiphon by late 197, Sulla sacked the Parthian capital, approaching from the southeast to cut off the escape of the Shah and to force a reorganization of the defending forces. With most of Parthia under its control and the armies of its great enemy in ruins around the capital, Rome added most of Mesopotamia to its empire, in the process forcing the king of Osroene to step down for a Roman governor - forming the provincia avgvstvm of Mesopotamia. Brought back to Rome for the personal trivmphvs of Sulla, Vologases V was soon ransomed back to Parthia for several decades of indemnities that were planned to amount to nearly 60 million denarii. This new source of revenue paled in comparison with the plunder of Persian cities and the royal treasury in Ctesiphon. Parthia survived this war but would never recover from the defeat - suffering from its lost wealth as well as the almost complete uprooting of its modest foliage in the construction of Roman war machines and kept down by constant but manageable tribute to Rome.
On his way to Rome, Sulla checked the situation in Armenia, finding that it had devolved into a squabbling for power among the local nobility. Upon entering the capital of Vagharshapat, the Romans were received with the highest honors in attempt to garner favor - news of the fall of Ctesiphon had already reached Armenia. One of the larger and more respected houses in the capital, the Koghuvtuni were named Kings of Armenia as a new foederatvs of Rome, forming a dynasty that the Romans would refer to as the Cogutunidae - replacing the earlier Arsacidae which had largely died or fled. Armenia would serve as a useful buffer for Rome in the East and could keep a close eye on the affairs of Persia. A few legions under Pescennius Niger were sent to Kartlia to secure its loyalty, forming another eastern client for Rome.
Sulla took the highs and lows of this victory. Although the sack of Ctesiphon had been a great victory for Rome, his decision to push the offensive rather than risk a lengthy siege cost tens of thousands of Roman lives and left Roman armies drastically undermanned, especially since the empire's manpower had only just recovered from the Germanic and Sarmatian Wars. However, these losses did not dissuade Sulla from his next campaign.
In the northern reaches of Western Europe, the famous general Avidivs Cassivs [2] had successfully subdued the Caledonii and kept British legions in line as governor of Britain from 182 to 189. When the Parthian War came to a close, these Picts had undergone something of a resurgence [3] so Sulla wasted little time bringing four legions of his veterans, blood hot from their glorification at the Triumph in Rome, to put an end to the threat posed by native tribes on the island.
His strategy was as ruthless as it was effective. Under the present climate of roving tribes, engaging in violence on both sides of the Vallvm Hadrianvm, Sulla selected several isolated villages not far north of the wall and had them systematically surrounded as their entire population was slaughtered. Messengers were sent to other Caledonian villages warning of the destruction of these villages by the "same tribes that had sacked Roman towns" and offering the aid of Rome against their rapine neighbors. The rumors polarized the people of southern Caledonia toward Rome; those who chose [4] to ignore this veneer of Roman aid armed themselves for a more organized conflict. As a result, the local enemies of Roman rule were brought to the forefront and the assimilation of Caledonia was accelerated [5].
Fighting continued in Britain until a letter arrived in the Senate in 205 declaring the conquest of Caledonia at an end. The guerrilla tactics of Rome's Caledonian enemies had prolonged the war, as Sulla chose a slow, cautious strategy rather than allow the guerrillas to dictate when and where battles were fought. As treaties were formed with the non-belligerent tribes and the scorched earth tactics [6] of the fighters lent credence to the official story, the conquest gradually unfolded in the favor of Rome. Caledonia was declared a new provincia avgvstvm separated from Britannia by Hadrian's Wall. During the war, the fleets in the Oceanvs Britannicvs had been greatly expanded and trade encouraged between Gaul and Britain, both as means to keeping the legions fed in the face of fewer local supplies. This growth in the number of ships in the region came at a high cost to the treasury, especially since the campaign offered few sources of revenue, but was sustained by the wealth coming in from Parthia.
Back in Rome, the period of absence of the emperor had been productive. Pescennius Niger had been governing Mesopotamia, assisted by Lvcivs Antistivs Bvrrvs in Syria Palestina after his consulship in 197, albeit with fewer legions than was ideal. Under the lack of troops, the legates in the region leaned heavily on auxiliaries [7]. Nevertheless, the Romans presented a persistent, united front to the Persians and the new status quo was maintained even while the Roman emperor looked elsewhere. In short, the Senate was busy integrating the new Roman territories and dealing with the loss of manpower [8]. As Sulla had forced senators to accept a larger share of the financial burden for public games and festivals, under the role of aedilis, Rome enjoyed only somewhat fewer spectacles than it had in the presence of Sulla [9]. Anti-piracy efforts that the Senate continued from the early part of Sulla's reign ensured a consistent annona for the urban poor and maintained a low price of grain, in conjunction with the recovery of Egyptian markets.
Meanwhile, in Alexandria, the academy of Galen reached its zenith. With the full support of the governor of Egypt, at the orders of the emperor, Galen exercised his freedom to study the human body. Criminals were brought to him on request, allowing him to open the skin and observe the action of human muscles, nerves, and arteries in vivo - to a deeper and more controlled degree than his time with injured gladiators in Rome. The heart was a common focus of his investigations, as an obviously core organ for one of the four humors. In his live studies, he determined the relative weight of blood in a human body and found that more than an ounce of blood left the heart with each beat. This discovery was incompatible with the prevailing theory that blood formed in the heart and liver before being moved in pulses to the organs where it was consumed, since not enough food was eaten to supply that quantity of blood. In its place, Galen hypothesized the circulation of blood through the organs then back to the heart, transforming from venous to arterial at the organs and the reverse at the heart [10]. Originally, Galen believed that venous blood was produced by the liver and arterial blood was formed in the heart by the combination of venous blood and air from the pulmonary artery by passage through the septum of the heart. By 212, careful observation had revealed that the septum was impermeable. Shortly before his death at the ripe age of 89, he added the theory of pulmonary circulation to his model of blood flow [11] and held that blood collected pneuma from its passage through the lungs. Before this final discovery about blood, Galen found that the heart was essential to the motion of blood through its vessels, amending his earlier belief that the arteries themselves were the source of its pulsations.
Regarding the brain and the nerves, Galen expanded on his model of two types of nerves - sensory and muscular - by identifying specific examples of nerves that controlled certain muscles and nerves that conveyed certain sensations (including the laryngeal nerve for voice and optic nerve for sight). Rejecting the theory of Herophilos that the nerves contained pneuma, Galen argued that a unique fluid filled their hollow channels [12] and conveyed instructions in the appropriate direction from the brain, about which he criticized past anatomists (notably Aristotle) for failing to realize its status as the seat of the psyche (intelligence). In this vein, Galen dubbed the nervous fluid psychon and hypothesized about its production in the ventricles of the brain, noting that they contained a raw, inert form of this spiritual fluid [13]. The flow of animal spirits through this fluid were the proposed mode of conduction for instructions from the brain (for motor nerves) and from stimuli on the body (for sensory nerves). His complete theory of the nervous system and human intelligence was published in 215 as De Substantia Intelligentiae, as part of his compilation of his life's work shortly before his death [14].
Aside from these fundamental studies of the two core physiological systems, Galen published hundreds of other discoveries throughout his life, covering as diverse anatomical features as the uterus, appendix, tongue, bones, and the eyes (failing to describe its optical properties). Indeed, his arguably greatest contribution to medicine was the enforcement of strict terms for different anatomical features, inventing most of the labels used today. In medical practice, Galen pioneered new surgical procedures for removing cataracts, for relieving intracranial pressure, and for decompression in the spine, noting that spinal injury could result in different forms of paralysis depending on the location of the damage.
Regarding infectious diseases, Galen expanded upon the miasmatic theory of infection and the humor theory of sickness, wherein a miasmatic essence pervaded from certain objects (corpses, swamps, sick people, etc.) and upset the balance of humors in the body. This miasma could purportedly settle on the skin to be passed by contact with others, noticing that doctors who had done dissections tended to have patients who returned with even greater illness. Following the usual practice for dressing wounds, Galen advocated strongly for the use of concentrated vinegar for removing this miasma and held that since it could spread from the sick to the healthy, even in spite of their balanced constitution, a quarantine of the sick would often be necessary. Strict procedures for quarantining the sick during, especially from the passengers of a ship, were described in the works of Galen, as the great plagues remained an obsession throughout his life.
As the accomplishments of Galen grew, many other medici followed his lead and took to using his more comprehensive texts on pharmacological remedies, surgical protocols, diseases, and human anatomy. His De Remediis published in 196 was a particularly famous codex - a veritable encyclopedia of diseases by their symptoms and treatments. In following his lead, some Pergamum doctors in 198 built a similar, albeit smaller, facility on the site of their famous aescvlapivm, referring to it by the secondary name of galenaria. Other healing centers following this generalized structure - involving a library, atrium for waiting patients, baths for cleansing the sick, and separate cells for quarantining the sick - appeared in other cities over the next few decades, notably Syracuse, Tyrus, and Corinthia, before Sulla returned to Rome and ordered the construction of the largest galenaria yet on the Campvs Martivs.
This building project marked the beginning of an extensive stay in Rome for Caesar Sulla, after holding his second trivmphvs in 205 to celebrate the conquest of Caledonia. Reaching the peak of his reputation with senators, soldiers, and commoners, the emperor was poised for administrative reform in the capital.

[1] More indirectly in the case of the Kartlian forces.
[2] At this time, Avidius Cassius has remarried. ITTL he marries Vibia Aurelia Sabina, the youngest daughter of Marcus Aurelius, at the designs of Claudius Pompeianus through the familial authority of her brother Sulla.
[3] Enough to cause trouble to Roman cities in northern Britain.
[4] People who disbelieved the official story would have had virtually no evidence against it and the subsequent belief that Romans were the real perpetrators would have been unfounded, although entirely true.
[5] Accelerated but not completed. At best this cold move would have reduced unrest following the conquest and engendered a stronger initial acceptance of Roman rule.
[6] Scorched earth in the sense of choosing to kill livestock and burn crops rather than allow them to fall to Roman legionaries, often killing the owners of these provisions in the process.
[7] This would be a low point in the number of eastern legions for Roman history. I have avoided stated explicit numbers for the legions here, since I lack records of the numbers under Marcus Aurelius, but suffice it to say it was somewhere around ten before the war and would at this time be around three.
[8] Here "Senate" refers to the legates as well, since they were senators and were the only ones with the requisite military authority to manage these affairs.
[9] Which is to say only as much as private wealth could afford, since Sulla did not allow any more public spending on games than he could get away with.
[10] Galen had earlier made the distinction between venous and arterial blood due to their color (or rather oxygenated and unoxygenated), although it is proper today to call blood from the lungs venous since it is defined by its direction relative to the heart.
[11] That is, he discovered that blood flowed to the lungs where it changed color. In his belief, here
pneuma (air) was added to the blood. His terms ITTL were
sanguis pneumata and
sanguis vacuua for arterial and venous blood respectively.
[12] Galen agreed with past anatomists that the nerves were hollow, although they are, strictly speaking, not, but held that they contained a fluid instead of air.
[13] In reality, cerebrospinal fluid which serves as cushioning for the central nervous system. Galen ITTL believed that the CSF was psychon absent the animal spirits that conferred its functional role.
[14] Less comprehensive statements of most of his discoveries would have long preceded these more systematic publications.

Coming up next will be some changes to the administrative structure of the Roman Empire - a paradigm shift of sorts in the relationship between Rome and its territories. In short, he will add an intermediate level of administration between province and Rome, one that accomplishes some of the work of the tetrarchial or diarchal divisions of the empire that were attempted IOTL, without compromising the military authority of a single ruler.

While we're throwing ideas out there, how about a henotheistic Christianity?
This never occurred to me as a possibility. I like the idea a lot actually. I'll give some thought into the form it could take, alongside the other possibly dominant henotheistic religions I will consider. It seems possible that the influence that emperors wielded over any early Christian Church would be sufficient to push a henotheistic stance, even in the face of a monotheistic Christian culture. If its founding emperor felt strongly about that change that is, as Constantine IOTL do not seem to have been.

IOTL, Galen spent a lot of time at the Museum in Alexandria. A quick look at Wikipedia shows that it was in Alexandria where Galen examined human skeletons and already dissected animals (though interestingly the wikipedia article states the taboos against human dissection extended to Egypt at this time, which I personally doubt, since I'm skeptical that what was not taboo in Egypt in the Hellenistic era suddenly became taboo in the imperial period). So there's definitely a lot of history OTL at least with Galen and Alexandria.
I'm inclined to agree with what you've said about the taboo and you've made a good case for the prominence of medical education in Alexandria. I've changed the location of the Galenic academy, in both my posts
Thanks for convincing me!
