Crossbow Fibula

Short Spring Crossbow Fibula

All of these fibula types have a short bilateral spring - usually only two or three winds each side.  Because of the short spring, theses fibulae do not actually look like a crossbow.  However, they are considered part of the crossbow fibula family.   Short spring crossbow fibulae are Germanic in origin.  They are descended from the early bent foot fibula.  Many short spring crossbow fibulae are made of iron.

Viminacium Type Short Spring Crossbow Fibula

Early Spring Crossbow Fibula with Rectangular Foot

Typology:  Genceva 21a

Dates:  c. AD 250 - 350.  Flourished AD 300 - 350.

Distribution:  Origin with Elbe Germans but spread southeast.  Found in Barbaricum from the Caucasus to eastern Hungary.  Used by Chernyakhov (Gothic) and Sarmatian cultures.  

Notes:  This type has a much wider spring and thus looks somewhat like a crossbow.  The head ends in a flattened section with a hole pierced in it for the spring-axis to pass through.

Early Spring Crossbow Fibula with High Catch

Typology:  Genceva 21b

Dates:  c. AD 180 - 200.  Alternately to AD 300.

Distribution:  Free Germany (Barbaricum) and the German Limes.

Notes:  This type has a much wider spring and thus looks somewhat like a crossbow.  It has two knobs on the bow similar to the Black Sea double knot kraftig profilierte type.

T-shaped Hinged

This group of crossbow fibulae have a short to medium length crossbar with a hinge in the middle.

Short Arm T-shaped Hinged Crossbow Fibula

Typology:  Bojovic XXXV.1-7; Genceva 23a

Dates:  c. AD 175 - 325/350, flourished c. AD 200 - 300.

Distribution:  Rhine and Danube Limes, likely Pannonia Limes origin.

Notes:  The type is found in many sub-types.

- with no head knob (Bojovic XXXV.1), late 2nd to early 3rd century AD.

- with a very small square or flat head knob  (Bojovic XXXV.2)

- with round knob (Bojovic XXXV.3)

- ends in blunt foot (Bojovic XXXV.4)

- knob on end of small triangular head-plate (Bojovic XXXV.5), mid-late 3rd century, Pannonia-Moesian.

- tall thin bow, small triangular head-plate without knob (Bojovic XXXV.6)

- flat bow, round knob (Bojovic XXXV.7) 

Others divide the type more simply into: head plate and head knob, head knob only and neither head knob nor head plate.

Image:  In this series of images, taken from the forum shop,  the short-arm T-shaped crossbar with hinge is clearly visible.  This example has a single small head knob.  Where the bow merges into the foot there are two triangular-shaped flanges with traces of copper wire.  This may be an imitative vestige of the ties used on bent-foot fibulae as the form of the foot is very close to the early bent-foot fibulae.  The head knob is like Bojovic XXXV.5 but the rest of the fibula, including the overall form, the foot and the flanges on the bow are like Bojovic XXV.1.  Likely a late XXV.1 type dating to circa AD 200 - 225.

Long Arm T-shaped Hinged Crossbow Fibulae

Typology:  Bojovic XXXV.8; Genceva 23b

Dates:  c. AD 300 - 325 (Bojovic), c. AD 225 - 275 (Genceva).

Distribution:  southern Pannonia and Moesia

Notes:  T-arms are long.  Bow is trapezoidal cross-section with ridging along top. 

T-shaped Hinged Crossbow Fibulae with 90° Angles and Wolf-Head above Foot

Typology:  Böhme 29

Dates:  c. AD 200 - 250

Distribution: Military sites, in Raetia and the upper Danube in particular.

Notes:  The bow has two 90˚ bends making it rectangular from the side.  Some exist with VTERE FELIX along the bow.

Trident-Head Crossbow Fibulae

Typology:  Hattatt xxx; Schmid # 217, Petkovic T.31E, Kovacevic T.47

Dates:  late 3rd to mid 4th century AD, but used into early 5th century.

Distribution:  Middle Danube origin - Upper Pannonia, Moesia Prima and Dacia.

Notes:  The head plate is wide and has three points or small knobs thus somewhat resembling a trident.  The head-plate covers a wide spring.  It is sometimes known as a Neptune trident fibula or Neptune fibula.  The trident-like head plate has led some scholars to believe that the type was used by the Upper Moesian Fleet (Petkovic).

Image:  Two trident head crossbow fibulae.  The upper example is complete though highly corroded.  It has no knobs on the head-plate and the join between the bow and the foot has two angular ridges.  The lower example is a different variant.  Though missing the right-hand side of the head-plate it is clear that the head-plate had three knobs on it (two remain).  There are also three small knobs at the back of the bow just before the foot.  Note that the foot of this type is quite short.  (SC Collection)

Multiple Bow Crossbow Fibulae

These small to medium sized fibulae have a bow divided into two or three parallel sections.   The bows can either be tall and thin, or wider and flat.

Bugelknopf Crossbow Fibulae

Typology:  Bojovic XXXIV; Genceva 40

Dates:  Dating is uncertain.  The type was used in the 4th and 5th centuries AD.  It likely started c. AD 350, though some sources say as early as AD 250.  It is unclear if it lasted throughout the 5th century or only for the first part.

Distribution:  Origin in "free" Germany, found the south through the Balkans.  

Notes:  Has a square, or occasionally triangular, section bow and a short foot.  There is a hole in the head for the axis-pin of a long spring.  Has a knob at the head.  The type is a Barbarian imitation of Crossbow fibulae with solid cross-bars although they are found in Roman military contexts as well.

Image:  A bugelknopf fibula without its spring.  Note the head-knob and the hole in the single flange for the spring's axis-pin to pass through.  There are still rust stains from the lost iron axis-pin.  There is a simple inscribed X on the side of the bow behind the knob.  (SC Collection)

Image: A bugelknopf fibula with spring.  The bilateral spring has a total of 13 or 14 winds.  Though the spring and pin is bronze, the axis-pin down the middle of the spring is iron and has caused rust staining.  (SC Collection)

Image:  A rare silver bugelknopf fibula.  There is still rust from the iron axis-pin of the missing spring.  Silver crossbow fibula such as this were generally worn by Roman military officers.  Though found at times on Roman military sites, bugelknopf fibulae are thought to be Germanic in origin.  This examples was likely from a Germanic officer in the Roman military and dates roughly to the Valentinianic and Theodosian eras.
