Silver Drachm of Peroz I (r. 457/459–484 CE): Typology, Iconography, and Crisis Coinage

Historical Context

Peroz I (Middle Persian: Pērōz, meaning 'Victorious') ascended the Sasanian throne following the death of his father, Yazdegerd II (r. 438–457 CE). His accession was contested by his elder brother, Hormizd III (r. 457–459 CE), initiating a two-year dynastic civil war. Supported by factions of the prominent Mihran aristocratic family and bolstered by military aid from the Hephthalite kingdom, Peroz defeated and executed Hormizd III in 459 CE to consolidate imperial rule.

The early decade of Peroz's reign was severely disrupted by an unprecedented seven-year drought and famine (ca. 464–471 CE). Medieval historiographical accounts, notably al-Tabari, record that imperial stability was preserved through decisive centralized intervention: the crown suspended land taxes, imported food supplies from neighboring provinces, and distributed treasury reserves directly to vulnerable populations to avoid systemic social collapse.

Externally, Peroz faced profound geopolitical instability on the northeastern frontiers. While he succeeded in subjugating the Kidarite Hunnic confederation and annexing regions in Sogdiana and Bactria between 466 and 468 CE, his subsequent military campaigns against the Hephthalites, led by Khushnavaz (Akhshunwar), proved disastrous. Peroz suffered severe defeats, was twice captured, and was forced to pay crushing silver indemnities—historically described as mule loads of silver drachms—to ransom his son and heir, Kavad I, and secure his own release.

To meet these monumental indemnities and finance military garrisons along the northeastern frontier, Sasanian mints increased drachm production to unprecedented volumes. In 484 CE, Peroz broke his treaty and launched an ill-fated final offensive against the Hephthalites near Balkh or Herat. The Sasanian heavy cavalry was lured into concealed trench traps, resulting in the annihilation of the royal army and the death of Peroz on the battlefield. While his defeat inaugurated decades of Hephthalite political hegemony over Iran, the massive output of his third-crown drachms permanently transformed late Sasanian monetary output and established an iconographic template that persisted into Arab-Sasanian and Central Asian Hunnic coinage.

Obverse Iconographic Composition

The obverse of the silver drachm presents the right-facing royal bust of Peroz I, rendered in high relief on a broad, thin silver flan delineated by a single dotted border. Documentation of museum comparator pieces illustrates standard physical parameters for the series, such as British Museum specimen 1920,0515.198, which measures 26 mm in diameter and weighs 4.150 g with a 3h die axis (nominal weights for well-preserved drachms typically range between 3.85 g and 4.25 g).

The royal portraiture depicts the king with a close-cropped, neatly curled beard, shaved cheeks, and a stylized mustache. His hair is gathered at the back of the neck in an expansive globular fabric-wrapped mass (korymbos). The ear is adorned with a royal earring consisting of three pearl drops, and beaded diadem ribbons rise behind the shoulders, framing the head. Peroz's costume consists of a royal tunic with a rounded pearl-bordered neckline, anchored across the chest by pearl pectorals leading to a central circular brooch.

The diagnostic typological element of Peroz's coinage is the royal crown, which developed through three primary stages across his reign:

• Crown 1 (Type I): A mural crown composed of stepped battlements, fronted by a lunar crescent and surmounted directly by a cloth korymbos; entirely without wings.
• Crown 2 (Type II): A stepped mural crown with a frontal crescent, where the korymbos rests within an apical crescent; no wings are present.
• Crown 3 (Type III / Definitive Mass Issue): A composite mural crown flanked by two expansive spread wings representing Verethragna (the Zoroastrian divinity of victory), with a frontal crescent, and the apical korymbos cradled within a lunar crescent.

Obverse Epigraphy and Inscriptions

The inscriptions on Peroz's silver drachms are written in Middle Persian utilizing the lapidary Inscriptional Pahlavi script. Primary numismatic reference corpuses record these texts through Latin-script transliterations and photographic facsimiles rather than modern reconstructed Unicode fonts.

Standard Short Formula

On the overwhelming majority of Type II and Type III drachms, the obverse legend is condensed to a concise right-field formula:

• Language: Middle Persian
• Transliteration: kdy pylwcy (occasionally contracted as kd pylwcy)
• Translation: 'King Peroz' (literally Kay Pērōz)
• Placement: Located in the right obverse field in front of the royal profile, arranged clockwise between 1 o'clock and 5 o'clock.

Divided and Full Imperial Formulae

Select issues preserve expanded imperial or ideological formulae across divided field placements:

• Abbreviated Imperial Layout: Verified on institutional comparator specimen British Museum 1920,0515.198, the legend is divided across the flan:
  • Behind head (11 o'clock): mzd
  • Before face (5 o'clock): kdy pylwcy
  • Combined Reading: mzd [kdy pylwcy] ('The Mazda-worshipping King Peroz')
• Complete Imperial Titulature: Attested on select Type I issues and early Type II specimens (such as Kunsthistorisches Museum Wien specimen GR 41987):
  • Transliteration: mzdysn bgy kdy pylwcy
  • Translation: 'The Mazda-worshipping Lord, King Peroz'
  • Placement: Arranged continuously along the outer perimeter, commencing behind the royal head at 11 o'clock and concluding before the face.

Reverse Iconographic Composition

The reverse composition centers on the Zoroastrian fire altar (ātašdān), the paramount symbol of imperial piety and royal legitimacy in Sasanian iconographic programs. The altar stands on a stepped plinth comprising two or three tiers, rising into a slender central cylindrical shaft tied at the center with flowing diadem ribbons that billow outward to the left and right. The shaft supports three stepped upper plates upon which the sacred sacrificial flame burns in multi-tiered tongues of fire.

The altar is flanked on either side by two attendant figures standing upright and facing inward toward the holy flame. The attendants wear royal drapery and rounded, globular headgear. Their hands hold ritual implements, traditionally identified as bundles of sacred twigs (barsom) or ceremonial staffs, with one hand occasionally raised toward the flames in an attitude of veneration.

In the upper fields flanking the fire, celestial astral symbols are depicted: an eight-pointed star occupies the upper left field, and a delicate upward-pointing lunar crescent occupies the upper right field. The entire scene is encircled by a single solid or finely beaded circular border.

Reverse Epigraphy and Inscriptions

The reverse contains two primary epigraphic fields situated vertically behind the standing altar attendants:

Left Field Epigraphy (9 o'clock)

• Dated Series (Type II): On early emissions of Type II, the left field carries an explicit Middle Persian numerical regnal year written in Pahlavi characters, such as dwk' (year 2), tlk' (year 3), extending through year 7 (and contested year 8).
• Undated Issues (Late Type II and all Type III): On undated drachms, the left field bears a prominent Pahlavi character or ligature. The interpretation of this glyph remains an active scholarly discussion:
  • MP Reading: Advanced by Nikolaus Schindel, Michael Alram, and Rika Gyselen, who interpret the character as a royal monogram ligature uniting the Aramaic heterogram MLKA ('King') with the initial letter P for Pērōz.
  • M Reading: Maintained in earlier reference catalogues and reflected in the British Museum collection records, which identify the character as an isolated Pahlavi letter M, serving as an unligatured heterogram for MLKA ('King') or an administrative control mark.

Right Field Epigraphy (3 o'clock)

The right field behind the right attendant contains an abbreviated administrative mint signature comprising two or three Middle Persian letters in Pahlavi script. Documented signatures across the series include:

• AT: Attributed to Ādurbādagān (Azerbaijan), as seen on British Museum comparator 1920,0515.198.
• DA: Attributed to Dārābgerd in Persis (Fars province), as documented on KHM Vienna comparator OR 6522.
• AS: Attributed by modern scholars to Asuristān (the capital province centered on Ctesiphon), though older scholarship debated an assignment to Aspahān (Isfahan).
• WH: Attributed to Veh-Andiyōk-Šābuhr (Gundeshapur in Khuzestan) or alternatively Veh-Ardashīr in Asuristan.
• BBA: Attributed to the mobile court mint (Dar / the royal camp or imperial capital).

Typology and Documented Variants

The standard classification of Peroz I's silver drachms is structured around crown typologies codified in foundational works by Robert Göbl and Nikolaus Schindel (SNS III).

Documented Variants and Specialized Issues

• Dated Regnal Sequence (Type II): Type II drachms bearing regnal years 2 through 7 (with contentious specimens attributed to year 8) represent the final consistently dated regular coinage of the fifth century prior to the systemic administrative reforms of Kavad I and Khusro I.
• Left-Facing Bust Special Issue (Type III): An exceptional ceremonial or presentation drachm emission depicting the royal bust facing left instead of right is attested from the Bishapur mint (BYŠ signature). This variant is documented in the Schaaf Collection (SNS Schaaf 404) and the Sunrise Collection (Nelson 2011, no. 950).
• Eastern Imitations (Hephthalite and Hunnic): Because immense quantities of Peroz's Type III drachms flowed east as tribute, regional workshops in Tokharistan, Bactria, and Sogdiana struck contemporary imitations. These are recognizable by coarser die cutting, corrupted pseudo-Pahlavi epigraphy, and occasional secondary Hephthalite countermarks (such as the ēb tamgha).

Scholarly Debates and Attribution Limitations

Chronology of Crown 3 Adoption

A primary numismatic debate concerns the date and political catalyst for the introduction of the winged Crown 3. Robert Göbl (1971) posited that Sasanian crown modifications reflected major dynastic ruptures, proposing that Crown 3 was adopted late in the reign (post-474 CE) following Peroz's release from Hephthalite captivity. In contrast, Nikolaus Schindel's (2004) comprehensive analysis of hoard distributions, die sequences, and dated Type II issues demonstrated that Crown 1 was confined to the 457–459 CE succession struggle, Crown 2 spanned regnal years 459 to 465 CE, and Crown 3 was inaugurated far earlier than Göbl assumed—around 465–468 CE. Numismatists continue to debate whether Crown 3 directly celebrated the victory over the Kidarites or coincided with the initial Hephthalite campaigns.

Reading of the Reverse Left-Field Glyph

Scholars remain divided over the functional and linguistic identity of the character at 9 o'clock on undated reverses. While Schindel, Alram, and Gyselen interpret it as a ligated royal monogram (MP for MLKA Pērōz), older corpora and current British Museum collection records classify it as an unligatured Pahlavi letter M representing the Aramaic heterogram MLKA ('King') or an administrative control mark.

Topographical Mint Attribution

Because Sasanian mint signatures consist of abbreviated, unvowelled Pahlavi consonants, several attributions remain unresolved. The signature AS is interpreted by Schindel and Gyselen as Asuristān (the central metropolitan province around Ctesiphon), whereas earlier numismatists traditionally attributed it to Aspahān (Isfahan). Similarly, WH is attributed alternatively to Veh-Andiyōk-Šābuhr (Gundeshapur) or Veh-Ardashīr.

Royal Ideology and the Title Kay

Peroz replaced the long-standing Sasanian imperial title šāhān šāh ('King of Kings') on standard drachms with the legendary title kdy (Kay). Scholars dispute whether this shift reflects a conscious imperial program to invoke the mythical Kayanian kings of Avestan tradition to galvanize Iranian resistance against Central Asian invaders, or indicates the rising political ascendancy of the Parthian Mihran clan, whose dynastic lore traced its lineage directly to the Kayanian heroes.
