Roman Coins of the Second Tetrarchy, 305-306 CE


The Second Tetrarchy: History. The Augusti (emperors) of the First Tetrarchy, Diocletian and Maximian, retired on May 1, 305. The Caesars Constantius and Galerius of the First Tetrarchy became the new Augusti and the title on their coins changed from Caesar to Augustus. New Caesars, Severus II and Maximinus II, were appointed, which began the "Second Tetrarchy" ("four rulers").  It ended with the death of Constantius in July 306. The Second Tetrarchy is defined by the reign of Constantius as Augustus. 

         The "Second Tetrarchy," May 1, 305 - July 306:
•  Augusti:  Constantius (in the west) and Galerius (in the east) 
•  Casears:  Severus II (in the west) and Maximinus II (in the east)  
•  Diocletian and Maximian retired "senior" Augusti

   Coins were issued for all six rulers. The coins for the retired augusti are discussed at the page "Abdication coins of Roman emperors Diocletian and Maximian." (Here is a page on coins of the First Tetrarchy.) 

What's new?  2020, March 20: Galerius HERCVLI VICTORI.  

The Second Tetrarchy: Coins.  The reign of Constantius as Augustus defines the Second Tetrarchy. His three co-rulers outlived him and after his death the complications introduced by the elevation of his son Constantine in July, and the usurpation of Maximian's son Maxentius in October ended the tetrarchal system.

Denominations issued include the:
•   follis, by far the most common denomination (below)
•   post-reform radiate, only at Alexandria and rare (below)
•   quarter-follis, only at Siscia (below and on its own page)
•   rare so-called "fractions" mostly from Trier, but a few from other mints (below and on their own page)
•   silver argenteus, rare and soon to be discontinued  (below and on its own page
•   gold aureus, rare and very expensive (Gold will not be discussed further on this page)

Folles. There were 14 active mints. Some minted only the previous GENIO POPVLI ROMANI type from the First Tetrarchy and others issued new types. A list of mints and the types they issued is far below. Retirement types for Diocletian and Maximian are not included because they have their own page).

New types listed (and illustrated below. Types continued from the First Tetrarchy are further below):  


•  Four new types with FIDES MILITVM, only for the Augusti Constantius and Galerius (Here)
   FIDES MILITVM, Fides seated left with standard in each hand, at Ticinum and Aquileia (Here)
   FIDES MILITVM, Fides standing left with standard in each hand, at Ticinum (Here)

   FIDES MILITVM AVGG ET CAESS NN, Fides seated with a standard in each hand, at Aquileia (Here)
   FIDES MILITVM AVGG ET CAESS NN, Fides standing with a standard in each hand, at Aquileia (Here)


•  Three new types with VIRTVS (Here)
   VIRTVS AVGG ET CAESS NN, Mars advancing right with spear and trophy over shoulder, only for the Caesars Severus II and Maximinus II. (Here) [later for Constantine as Caesar at Ticinum]  (Here)
   VIRTVS AVGG ET CAESS NN, Prince standing left with captive at feet left, holding small Victory and spear and shield, only for the Caesars and only at Aquileia [later for Constantine as Caesar at Ticinum] (not illustrated)

   VIRTVS AVGG ET CAESS NN, horseman riding right, spearing a foe, for all four rulers at Aquileia (Here) [and later for Constantine as Caesar and Severus II as Augustus]

•  PERPETVITAS AVGG, Roma seated left, helmeted, only for Severus II at Alexandria. (Here

•  Two very similar Concordia types
    CONCORD IMPERII, Concordia standing front, only for Maximinus II at Alexandria. (Here)
    CONCORDIA IMPERII, Concordia standing front, only for three Caesars, Severus II, Maximinus II, and Constantine, at Siscia. (Here)


 
FIDES MILITVM.  There are four new types with FIDES MILITVM issued for the new Augusti, Constantius and Galerius, but not for the Caesars, at Ticinum and Aquileia. 


Constantius as Augustus
28 mm. 10.38 grams.
IMP C CONSTANTIVS PF AVG
Laureate head right

FIDES MILITVM
Fides seated left holding standard in each hand.
S T in exergue.
RIC Ticinum 55a "c. 305".

Fides types were issued only for the Augusti and only at Ticinum and Aquileia.

(An example for Galerius)

Galerius as Augustus
29 mm. 10.21 grams.
IMP MAXIMIANVS PF AVG
Laureate head right
FIDES MILITVM, Fides standing left with standard in each hand
VI in right field, AQS in exergue.
RIC Aquileia unlisted but would be 56b "c. 305". 

Note:  The obverse legend includes "MAXIMIANVS" but the coin is of Galerius, not Maximian. The portrait lacks the distinctive upturned nose of Maximian and the co-ruler in this issue is Constantius as Augustus. There is a page on how to distinguish the ruler we call Galerius from Maximian

 


Notes about this page:
  Almost all folles are like the first two in that they have "Laureate head right." Descriptions of obverse portraits below are omitted unless they are different.
  The essential reference is RIC (Roman Imperial Coinage) volume VI by C. H. V. Sutherland, 1973. Many varieties have been discovered since RIC VI was written, but there is still no better way to get both an overview and details of the coinage.



Constantius as Augustus
29-27 mm. 8.73 grams.
IMP CONSTANTIVS PF AVG
FIDES MILITVM AVGG ET CAESS NN
Fides seated left holding standard in each hand
AQS
RIC Aquileia 62a

 

 



Constantius as Augustus

IMP CONSTANTIVS PF AVG
FIDES MILITVM AVGG ET CAESS NN

AQS
RIC Aquileia 60a

(This type for Galerius)

 

 

 


Virtus. The Caesars did not participate in the Fides issues from Ticinum and Aquileia. They had types with Virtus. The personification of Virtus is virtually identical with Mars, so the figure walking may be Virtus but is often called Mars.


Severus II as Caesar 
26-25 mm. 7.92 grams.
SEVERVS NOB CAESAR
VIRTVS AVGG ET CAESS NN, Mars advancing right with spear in right hand and holding trophy over his left shoulder.
PT in exergue.
RIC Ticinum 60a, "c. 306."

This type was also issued for Maximinus II, but not the Augusti.

 

 

The most striking new design has both an unusual helmeted head left and a horseman riding right.

Galerius as Augustus
28-25 mm. 8.24 grams.
IMP C MAXIMIANVS PF AVG
Bust in crested helmet left, holding scepter over far shoulder and shield in left.
VIRTVS AVGG ET CAESS NN
Horseman (emperor) galloping right, shield on left, spearing kneeling foe with dropped shield, prostrate foe below.
AQS  in exergue
RIC Aquileia 81a "25 July 306-c. March 307."

[This type began under the Second Tetrarchy, but this particular example is from after Constantine was added to the type. The only difference is in the obverse legend. This one has "IMP C" and the earlier one has just "IMP".]


PERPETVITAS AVGG at Alexandria.  At Alexandria, each ruler had his own type. This type was for Severus II.

Concordia.  There are two very similar types with Concordia.
    CONCORD IMPERII at Alexandria, for Maximinus II only (next coin), and
    CONCORD-IA IMPERI at Siscia, for Maximianus II, Severus II, and also Constantine as Caesar.


Maximinus II as Caesar.

At Alexandria each of the four rulers had only his own type. Severus II had  PERPETVITAS AVGG (above). Constantius had HERCVLI VICTORI and Galerius had IOVI CONS CAES--types which were continued from the First Tetrarchy. 


Maximinus II as Caesar

SISB  in exergue
RIC Siscia 174b variety (officina B. Only Γ is listed.)

 

(An example for Severus II)

 

It is not certain this coin was issued during the Second Tetrarchy, even though the issue includes Severus II as Caesar. Read a page on assigning dates of issues.

Follis types that were continued from the First Tetrarchy are below, after the other denominations of the period. 

 

Other denominations. Other denominations include
•   post-reform radiate (next below)
•   quarter-follis, only at Siscia (below and on its own page)
•   rare so-called "fractions" mostly from Trier, but a few from Rome (below and on its own page)
•   argenteus, rare and soon to be discontinued  (below and on its own page

 

Post-Reform Radiate. The post-reform radiate (a.k.a. "radiate fraction") denomination was introduced in the reform of c. 294 and, although it is common, it was only issued at a few mints and never became a major part of the coinage system. It is not certain how the reform pegged its values of the denominations. Some authors think these new radiates were 2 denarii and five of these made one follis of 10 denarii (prior to Diocletian's Edict of Maximum prices). Where did the old aurelianus fit in?  I think it was also pegged at 2 denarii which explains seven things. The new radiate




Constantius as Augustus.
21-19 mm. 3.12 grams.
IMP CONSTANTIVS PF AVG
Radiate, draped, and cuirassed bust right
CONCORDIA MILITVM
  R  in middle field
ALE  in exergue
RIC Alexandria 59aB.

All four rulers participated in this issue and it was continued for Severus II as Augustus and Constantine as Caesar. (A page about radiate fractions.)

 


Quarter-follis.  The quarter-follis denomination was issued only at Siscia at the beginning of the Second Tetrarchy. Before the 1990's, it was rare in the west because it had circulated in the region near Siscia which was behind the Iron Curtain. Now, it is far more common than the rarity ratings in RIC have it. It was issued for all four tetrarchs plus Maximian as Augustus. How Maximian fits in with the other four with Second Tetrarchy titles remains unexplained.


Constantius as Augustus
19 mm. 2.34 grams.  That is much smaller than the 28 mm follis and about 1/4 the weight. 
CONSTANTIVS AVG
GENIO POPVLI ROMANI
RIC Siscia 169a "R2," but actually much more common than that.

There is a page devoted to quarter folles. It is not known why Siscia issued this smaller denomination with the old GENIO POPVLI ROMANI design and why they did not issue the full-size follis of this design when so many other mints did. 


 

Fractions.  For some unknown reason a few fractional denominations were issued c. 290-321, mostly at Trier, which celebrated anniversaries with small issues of small laureate coins which expressed vows. We follow Zschucke in calling them "fractions." (These are not the larger so-called "quarter follis" coins of Siscia above). A few are from Rome, Lyon, Ticinum, and Siscia.  Zschucke lists 263 fractional varieties from Trier. We do not know the ancient names of these small denominations, nor are we certain how they relate to the other denominations of Diocletian's coin reform of c. 294, the "follis" or "nummis," the post-reform radiates, and the silver argenteus. Zschucke calls them "1/8 [follis]" (the smaller ones) and "1/4" (the larger ones) with a few later ones under Constantine called "1/2."  Unusual small coins like these were issued in the names of emperors Diocletian through Crispus and Constantine II.

This coin marks the promotion of Severus II to Caesar.

Severus II, Caesar 305-306. Augustus 306-307.

  (For more about fractions, see this page on fractions.)
 

Argenteus.  There are very rare argentei with a second-tetrarchy title. They show that the argenteus denomination--begun c. 294--continued into the second Tetrarchy.

  (For much more about argentei, see the page on argentei.)


 


Types of folles continued from the First Tetrarchy.  Six follis types had been used previously under the First Tetrarchy. Of course, for the Second Tetrarchy the titles change. The types are: 

•  GENIO POPVLI ROMANI, for all four rulers at London, Trier, Lugdunum, Serdica, Heraclea, Nicomedia, Cyzicus, and Antioch. (Here)
        (Siscia did not use this legend on folles, but did on the new quarter-follis denomination.)
•  SACRA MONETA AVGG ET CAESS NOSTR, for all four at Siscia and Rome. (Here)
•  SALVIS AVGG ET CAESS FEL KART, for all four from Carthage. (Here)
•  GENIO AVGG ET CAESS NN, Genius standing, for the Caesars at Cyzicus. (Here)
•  HERCVLI VICTORI, only for Constantius at Alexandria and for all four at Siscia. (Here)
•  IOVI CONS CAES, only for Galerius at Alexandria.  (Here)

 


GENIO AVGG ET CAESARVM NN at Cyzicus. This type (ending CAESS NN) had been issued for the Caesars of the First Tetrarchy at Cyzicus (Here). It continued for the Caesars of the Second Tetrarchy--only the Caesars and only at Cyzicus.

Alexandria. Under the Second Tetrarchy Alexandria issued HERCVLI VICTORI for the western Augustus and IOVI CONS CAES for the eastern Augustus, but not for the Caesars. Under the First Tetrarchy HERCVLI VICTORI had been issued both for the western Augustus and Caesar and IOVI CONS CAES for both the eastern Augustus and Caesar. Also, the HERCVLI VICTORI type was issued at Siscia under the Second Tetrarchy.

SACRA MONETA.  The second most common type under the First Tetrarchy, SACRA MONETA, was continued only at Rome and Siscia.  Rome used the legend SAC MON VRB AVGG ET CAESS NN (note the addition of "VRB") for all four and Siscia the more-usual SACRA MONET AVGG ET CAES NN for all four. Two examples are illustrated here and this type has its own page.

Examples from the time of the Second Tetrarchy are next and many more examples from under the First Tetrachy can be seen on their own pages

The coins of Severus II as Caesar are from the Second Tetrarchy, or just a short while longer. According to the tetrarchal system the Caesar was promoted when the position of Augustus became vacant. Severus II was Caesar in the west and was duly promoted after the death of the western Augustus, Constantius. However, there may have been a time lag before Severus II was acknowledged Augustus while Galerius, the eastern Augustus, gave his advice and consent.

At Trier there was an issue for the four rulers with Genius naked (not illustrated here for Trier, but the coins above show the type) as had been the only depiction of Genius since the design's inception in 294, followed by an issue with loins draped that included Constantine as Caesar. Differences like these affect dating. The next two coins are from that "loins draped" issue which is discussed in detail on this page about dating

Maximinus II was Caesar from May 305 until early 309 when he became Augustus, so his coins as Caesar may or may not be issued during the Second Tetrarchy.

These control marks and mintmark are used on an issue at Trier where Genius is naked and only the four rulers participate. This coin with "loins draped" is from a second part of that time period in which five rulers, including Constantine participate. Maybe the elevation of Constantine was enough to change the presentation of Genius and this type is later than the Second Tetrarchy. Or, maybe the issue was in progress when Constantine was elevated and he joined it late.

 



Mints of the Second Tetrarchy and their follis types. "GPR" abbreviates "GENIO POPVLI ROMANI for all four tetrarchs." This list does not include retirement types for Diocletian and Maximian.

 


History: The beginning of the Second Tetrarchy. 

Constantius added Spain to his territory of Gaul and Britain. Severus II got Africa, Italy, and Pannonia (taken away from Galerius). Galerius got all of Asia Minor (which had been part of Diocletians' territory) west of the Tarsus mountains, which increased his base significantly. Maximinus II got Syria and Egypt. 

When Diocletian decide to retire he had to select new caesars. However, he had been seriously ill for over a year and not as strong a personality as he had been. Maximian had an eligble son, Maxentius, and Constantius had an eligible son, Constantine. But Galerius, also in the east, had his own candidates. Somehow it was decided that Maxentius was unsuitable and that it would not work to appoint Constantine and not Maxentius. So Galerius got his way with both new caesars being his choices. 

The end of the Second Tetrarchy. The "Second Tetrarchy" only lasted until Constantius died in July 306. At that time his son Constantine was promoted without the advice and consent of the other rulers, either by the dying Augustus Constantius or by the army after his death. The orderly system that had created the Second Tetrarchy lasted less than two years. In short summary, after Constantius died in July 306:

•  Constantine was acclaimed emperor by the army when Constantius died in July 306, or by Constantius as he was dying
•  Severus II was elevated to Augustus in the west by Galerius (the remaining, eastern, Augustus). There may be some time lapse because there are issues (at Trier and Siscia) with both Severus and Constantine as Caesars. (Discussed on the page about dating)

•  Maxentius, son of Maximian, seized power in Rome in October 306 when Severus was away in the north
•  Maximian came out of retirement to join him in November, and resumed the title Augustus and began his "second reign"
•  both Maxentius (early[?] 307) and Constantine (July 307) took the title Augustus (There are issues with Maxentius as Augustus and Constantine as Caesar) and 
•  Severus II was killed in the summer of 307 after failing to retake his territory which included the city of Rome.

Each of these events is reflected in the coinage. There is a page on coins after the Second Tetrarchy, from 306-324. There is also a long page on the events that lead Galerius to award the title FIL AVG to Constantine and Maximinus II during 309-310.
