Errett Albert Bishop (July 14, 1928 - April 14, 1983) was an American mathematician known for his work on analysis and a professor at the University of California at San Diego. He expanded constructive analysis in his 1967 Foundations of Constructive Analysis, where he proved most of the important theorems in real analysis by constructive methods. (see https://en.wikipedia.org/wiki/Errett_Bishop).
He was also a great father and a fun-loving guy who would take his family biking, surfing, snorkeling, camping, etc. He enjoyed going to auctions, where he would often pick up an interesting artifact or a piece of art. Errett's son, Edward, in the photograph with his father on the right, describes his childhood home as half junk-yard, half museum. Errett especially loved ancient coins, and he was one of the founding members of the Ancient Coin Club in San Diego.
The Errett Bishop Collection includes over 1000 Ancient Greek, Roman Republic, Roman imperial, Roman provincial, Celtic, Judaean, Byzantine and other ancient coins collected from about 1960 to 1982. The collection includes 136 coins from Ptolemaic and Roman Egypt. The variety of types and the range from inexpensive to beautiful showcase coins means there are coins in this collection for almost every collection and every budget. Due to the size of the collection, it will be some time before they are all added to the shop. Keep looking here or in our recent additions to see them as we add them.
Roman Republic, Cast Aes Grave, c. 270 B.C.
In 270 B.C., Rome's subjugation of Italy was completed by the recapture of Rhegium from the Mamertines and the defeat of the Brutians, the Lucanians, the Calabrians and the Samnites. The town of Rhegium was then restored by the Romans to its original Greek inhabitants.RR93747. Aes grave (cast) triens, Crawford 18/3, Sydenham 17, Thurlow-Vecchi 10, ICC 35, HN Italy 281, Russo RBW -, VF, dark green patina, earthen deposits, minor casting flaw on edge, weight 97.090 g, maximum diameter 47.1 mm, die axis 0o, Rome mint, c. 270 B.C.; obverse head of horse right, (mark of value); reverse head of horse left, (mark of value) below; from the Errett Bishop Collection, 97 grams! 47 mm!; $1900.00 (1558.00)
Seleukid Kingdom, Seleucus I Nikator, 312 - 280 B.C.
Seleukos (Seleucus) founded the Seleukid Empire and the Seleukid dynasty which ruled Syria until Pompey made it a Roman province in 63 B.C. Seleukos was never one of Alexander the Great's principal generals but he commanded the royal bodyguard during the Indian campaign. In the division of the empire after Alexander's death Seleukos did not receive a satrapy. Instead, he served under the regent Perdikkas until the latter's murder in 321 or 320. Seleukos was then appointed satrap of Babylonia. Five years later Antigonus Monophthalmus (the One-eyed) forced him to flee, but he returned with support from Ptolemy. He later added Persia and Media to his territory and defeated both Antigonus and Lysimachus. He was succeeded by his son Antiochus I.GY95974. Silver tetradrachm, cf. Houghton-Lorber I 177; Newell ESM 314; BMC Seleucid p. 3, 33 - 34; HGC 9 18c (R1-R2), aVF, high relief head of Zeus, old cabinet toning, flow lines, porosity, light marks, minor edge flaw on reverse, weight 16.251 g, maximum diameter 26.9 mm, die axis 180o, Susa (Shush, Iran) mint, c. 295 - 280 B.C.; obverse diademed head of Zeus right; reverse Athena driving biga of horned elephants, BAΣIΛEΩΣ (king) downward on left, ΣEΛEYKOY in exergue, spearhead (control) above right, A(or E or M over Ω?, obscure, control) lower right before elephants; from the Errett Bishop Collection; $1600.00 (1312.00)
Aspendos, Pamphylia, 333 - 250 B.C.
After Alexander took Perga peacefully, Aspendos sent envoys to offer surrender if he would not take the taxes and horses formerly paid as tribute to the Persian king. Agreeing, Alexander went on to Side, leaving a garrison behind. When he learned they had failed to ratify the agreement their own envoys had proposed, Alexander marched to the city. The Aspendians retreated to their acropolis and again sent envoys to sue for peace. This time, however, they had to agree to harsh terms - they would host a Macedonian garrison and pay 100 gold talents and 4,000 horses annually.
This type is a late example and likely among the last of the wrestler and slinger staters. Struck during economic crisis, perhaps resulting from the harsh terms set by Alexander after their treachery, the flans are underweight, crudely cast and appear to be of debased silver. The wrestlers and slinger are carelessly depicted. It is not as attractive as earlier examples but it is certainly much scarcer.GS95992. Silver stater, Tekin Series 5, SNGvA 4576, SNG BnF 122, SNG Cop 240, Arslan-Lightfoot -, Choice gVF, attractive style, toned, obverse edge beveled, edge cracks, weight 10.440 g, maximum diameter 24.7 mm, die axis 0o, Aspendos mint, 333 - 250 B.C.; obverse two wrestlers grappling, nude, wrestler on left holds the right wrist of his opponent with his right hand and right forearm with his left hand, E between their legs, tiny die break on right, beveled edge; reverse slinger, wearing short chiton, discharging sling to right, EΣTFE∆IY upward behind, O between legs, clockwise triskeles of human legs above club on right, round border of dots; from the Errett Bishop Collection; scarce; $720.00 (590.40)
Seleukid Kingdom, Antiochus IX Cyzicenus, 113 - 95 B.C
After Antiochus IX's father died, his uncle Demetrius II Nicator took the throne. For his safety, his mother, Cleopatra Thea, sent him to Cyzicus (leading to his nickname). He returned to Syria in 116 B.C. to claim the throne from his half-brother Antiochus VIII Grypus, with whom he eventually divided Syria. He was killed in battle by the son of Grypus, Seleucus VI Epiphanes.GY95956. Silver tetradrachm, Houghton-Lorber II 2384; Houghton CSE 725; Babelon Rois 1467; BMC Seleucid p. 92, 6; HGC 9 1288k (R2), gVF, well centered, dark old cabinet toning, old scratches, light deposits, weight 15.977 g, maximum diameter 29.2 mm, die axis 0o, Sidon (Saida, Lebanon) mint, 2nd reign, 113 - 112 B.C.; obverse diademed head of Antiochos right; reverse Athena standing left, Nike in right hand, resting left hand on grounded shield, spear behind, BAΣIΛEΩΣ ANTIOXOY in two lines downward on right, ΦIΛO−ΠATOPOΣ downward on left, ΣI∆Ω/IEP / AΣY in 3 lines over outer left, Σ (year 200) in exergue; from the Errett Bishop Collection; very rare; $630.00 (516.60)
Seleukid Kingdom, Antiochus III the Great, c. 223 - 187 B.C.
At the age of eighteen, Antiochus III inherited a disorganized state. Much of Anatolia had been lost and the easternmost provinces had revolted and broken away. After some initial defeats, Antiochus took Judaea from Ptolemaic Egypt and then conquered Anatolia, earning him the epithet "the Great." In 192 B.C. Antiochus invaded Greece with a 10,000-man army, and was elected the commander in chief of the Aetolian League. In 191 B.C., however, the Romans routed him at Thermopylae, forcing him to withdraw to Anatolia. The Romans followed up by invading Anatolia and defeating him again. By the Treaty of Apamea 188 B.C., Antiochus abandoned all territory north and west of the Taurus, most of which the Roman Republic gave either to Rhodes or to the Attalid ruler Eumenes II, its allies. Many Greek cities were left free. As a consequence of this blow to the Seleucid power, the provinces which had recovered by Antiochus, reasserted their independence. Antiochus mounted a fresh eastern expedition. He died while pillaging a temple of Bel at Elymaοs, Persia, in 187 B.C.GY95972. Silver tetradrachm, Houghton-Lorber I 967 var. (one diadem end upward), Mektepini Hoard 636 var. (same), HGC 9 447g (R2), VF, light bumps/marks, slightest corrosion/porosity, weight 16.983 g, maximum diameter 28.1 mm, die axis 0o, Western Asia Minor, uncertain mint, c. 203 - 187 B.C.; obverse Antiochos' diademed head right, youthful, jutting nose, pursed lips, diadem ends straight down behind head; reverse Apollo seated left on omphalos, nude, examining arrow in right hand, resting left hand on bow grounded behind, bow ornamented with two sets of two disks, BAΣIΛEΩΣ (king) downward on right, ANTIOXOY downward on left, monograms outer left and right; from the Errett Bishop Collection; very rare; $400.00 (328.00)

This coin is an obverse die match to a coin struck by the neighboring city, Alabanda, Caria, SNG Mόnchen 464, RPC Online VI T5384. Dies shared by more than one city in the region were first discovered by Konrad Kraft in 1972. Groups of smaller cities in Anatolia shared traveling mints, which would sometimes use the same obverse dies for more than one city.RP92646. Bronze AE 30, Apparently unpublished; RPC Online -, SNG BnF -, SNGvA -, SNG Cop -, BMC Caria -, F, porous, turquoise and earthen adhesions, reverse flatly struck, weight 11.787 g, maximum diameter 29.7 mm, die axis 180o, Apollonia Salbace (Edremit, Turkey) mint, 13 Mar 222 - Mar 235 A.D.; obverse AYT K M AYP CEY AΛEΞAN∆PO-C, laureate, draped, and cuirassed bust right, seen from behind; reverse CTPA AΓAΘEINOY TOY IH AΠOΛΛΩNIATΩN (strategos Agathinos, son of Hie.(?), Apollonia), Zeus standing slightly left, head left, wearing himation and chlamys, eagle in right hand, long scepter vertical in left hand; from the Errett Bishop Collection; extremely rare, this is the only specimen of the type known to FORVM; $280.00 (229.60)
Macrinus, 11 April 217 - 8 June 218 A.D.
Macrinus was Praetorian Prefect for Caracalla but arranged Caracalla's assassination and seized power. He and his son were accepted by the senate. The Syrian legions, inspired by Julia Maesa, Caracalla's aunt, revolted after he concluded an unfavorable peace with the Persians. He was defeated and executed.SL92493. Orichalcum sestertius, RIC IV 121 (S), BMCRE V 113, Cohen IV 79, SRCV II 7391, Hunter III -, NGC F, strike 4/5, surface 1/5, scratches (577028-007), weight 19.150 g, maximum diameter 30.7 mm, die axis 0o, Rome mint, 11 Apr 217 - 31 Dec 217 A.D.; obverse IMP CAES M OPEL SEV MACRINVS AVG, laureate and cuirassed bust right, from the front; reverse PONTIF MAX TR P P P (high priest, holder of Tribunitian power, father of the country), Felicitas standing facing, head left, long caduceus in right hand, cornucopia in left hand, drapery over left arm, S - C (senatus consulto) flanking across field below center; from the Errett Bishop Collection; NGC| Lookup; $260.00 (213.20)
Seleukid Kingdom, Demetrius I Soter, 162 - 150 B.C.
As required by the Treaty of Apamea, Demetrius, the son of Seleucus IV, was held in Rome as a hostage. After Antiochus IV (his uncle) died, he claimed the right to rule but Rome preferred Antiochus V, a weak child. Demetrius escaped, was welcomed in Syria and took his throne. Antiochus V and his regent were executed. Demetrius defeated Judas Maccabaeus and restored Seleukid control over Judaea.GY95964. Silver tetradrachm, Houghton-Lorber II 1637a; SNG Spaer 1257; Newell SMA 81; BMC Seleucid p. 47, 33 & pl.

Romano-British Empire, Carausius, Mid 286 - Spring or Early Summer 293 A.D.
The quantity of PAX coinage issued by Carausius probably exceeded the entire output of all his other types combined. The type was an appeal by the usurper Carausius for peace with the "official" emperors. Diocletian and Maximian did not recognize Carausius as emperor, nor did they reciprocate his desire for peace.RA93350. Billon antoninianus, Webb Carausius 171; RIC V-2 143 (R); Cohen VII 239; SRCV IV 13665; Hunter IV 50, aVF/F, well centered, minor porosity, weight 4.138 g, maximum diameter 22.2 mm, die axis 0o, Londinium (London, England) mint, c. 292 - early 293; obverse IMP C CARAVSIVS P F AVG, radiate, draped, and cuirassed bust right, from the front; reverse PAX AVGGG (the peace of the three emperors), Pax standing half left, head left, olive branch in right hand, long scepter transverse in left hand, S - P flanking across field, MLXXI in exergue; from the Errett Bishop Collection; rare; $220.00 (180.40)
Roman Macedonia, "Thasian" Type, c. 148 - 80 B.C.
This Dionysos / Herakles type was first struck by Thasos itself on the island and in its continental territories in the South of the Balkans, c. 168 - 148 B.C. After Rome took control of the area, "Thasian" types were struck by Roman authorities, c. 148 - 80 B.C., mainly in Macedonia but also, perhaps, by mobile military mints on campaigns. Imitatives were also struck by at least several tribal groups (mainly Celtic or mixed enclaves) from as early as 120 - 100 B.C. to about 20 - 10 B.C.GS95927. Silver tetradrachm, Prokopov Thasos, group XII, monogram 6, 759 var. (VAE1/R603); Lanz (Kostial) 963 - 967; SNG Cop 1040 ff., Choice VF, toned, light graffito (AP?) obverse right, bumps and marks, edge crack, weight 16.835 g, maximum diameter 31.7 mm, die axis 0o, Roman provincial or military mint, c. 148 - 80 B.C.; obverse head of Dionysos right, wearing taenia and wreathed in flowering ivy; reverse HPAKΛEOYΣ ΣΩTHPOΣ ΘAΣIΩN, Herakles standing half left, nude but for Nemean lion's skin on left arm, resting right hand on grounded club before him, left hand on hip, (MH monogram) inner left; $210.00 (172.20)
"The real numbers, for certain purposes, are too thin. Many beautiful phenomena become fully visible only when the complex numbers are brought to the fore." (Bishop 1967, Ch. 5, Complex Analysis, p. 113)
"The primary concern of mathematics is number, and this means the positive integers...In the words of Kronecker, the positive integers were created by God. Kronecker would have expressed it even better if he had said that the positive integers were created by God for the benefit of man (and other finite beings). Mathematics belongs to man, not to God. We are not interested in properties of the positive integers that have no descriptive meaning for finite man. When a man proves a positive integer to exist, he should show how to find it. If God has mathematics of his own that needs to be done, let him do it himself." (Bishop 1967, Ch. 1, A Constructivist Manifesto, p. 2)
