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.
Lucilla, Augusta c. 164 - 182 A.D., Wife of Lucius Verus
For Roman wives, piety often meant accepting neglect. It was not considered adultery for a Roman husband to have sex with slaves or unmarried women. The historian Spartianus wrote that after Lucilla complained, Lucius Verus reproached her: "Uxor enim dignitatis nomen est, non voluptatis" (Wife is the name of dignity, not bliss). RB92463.

Claudius, 25 January 41 - 13 October 54 A.D.
A "Tiber patina," sometimes called a river patina, is technically not a patina at all. Rather, submersion in anaerobic fresh water or mud on a river bottom has prevented a normal patina from forming. The shiny original surfaces of the coin often becomes subdued and grainy or porous. Curvy lines of corrosion, with an appearance similar to worm holes in wood, are seen on this coin and are common on river found coins. We don't know what causes these strange flaws. SL89519. Orichalcum sestertius, RIC I 99, SRCV I 1853, BMCRE I 124, Cohen I 85, NGC Ch VF, strike 4/5, surface 1/5 (24900381-001), Tiber patina with porosity and corrosion typical of a fresh water find, weight 23.735 g, maximum diameter 35.4 mm, die axis 180o, Western branch "barbarous" mint, c. 41 A.D.; obverse TI CLAVDIVS CAESAR AVG P M TR P IMP, laureate head right; reverse SPES AVGVSTA, Spes walking left, flower in extended right hand, raising fold of chiton with left hand, S C (senatus consulto) in exergue; from the Errett Bishop Collection, photos taken before certification, now in a NGC holder; $300.00 (€264.00)
Septimius Severus, 9 April 193 - 4 February 211 A.D.
Victory or Nike is seen with wings in most statues and paintings, with one of the most famous being the Winged Victory of Samothrace. Most other winged deities in the Greek pantheon had shed their wings by Classical times. Nike is the goddess of strength, speed, and victory. Nike was a very close acquaintance of Athena and is thought to have stood in Athena's outstretched hand in the statue of Athena located in the Parthenon. Victory or Nike is also one of the most commonly portrayed figures on Greek and Roman coins. RS92475. Silver denarius, RIC IV 423 (S) var. (...CAE L SEV...); RSC III 696 var.

Nero, 13 October 54 - 9 June 68 A.D.
The reverse legend translates, "The gates of Janus' temple are closed because peace of the Roman people is set on both land and sea." On the rare occasions when Rome was not at war the doors of the 'Twin Janus' were ceremonially closed, an event Nero commemorated extensively on the coinage of 65 - 67 A.D. -- Roman Coins and Their Values, Vol. 1 by David R.

Nero, 13 October 54 - 9 June 68 A.D.
Quadrantes, like quinarii, were issued only occasionally, perhaps exclusively for imperial distributions. Suetonius reported that, from the roof of the Basilica Julia "Caligula threw coins among the people." Perhaps this small coin was thrown to the crowd by the Nero himself at a similar event.RB89528. Orichalcum quadrans, BMCRE I p. 258, 300 (same legend breaks); Mac Dowall WCN 342a; RIC I 258, BnF I 353; Cohen I 110; Hunter I -; SRCV I -, aEF, nice red and green patina, porosity, obverse slightly off center, weight 1.910 g, maximum diameter 13.7 mm, die axis 180o, Rome mint, c. 64 - 66 A.D.; obverse NERO CLAV CAE AVG 16, owl, with wings spread, standing facing on garlanded altar, snake winding up the right side of the altar; reverse GER P M TR P IMP P P, upright olive-branch, three tiny dots (mark of value) below, S - C (senatus consulto) flanking at sides; from the Errett Bishop Collection; $225.00 (€198.00)
Galba, 3 April 68 - 15 January 69 A.D.
The pileus liberatis was a soft felt cap worn by liberated slaves of Troy and Asia Minor. In late Republican Rome, the pileus was symbolically given to slaves upon manumission, granting them not only their personal liberty, but also freedom as citizens with the right to vote (if male). Following the assassination of Julius Caesar in 44 B.C., Brutus and his co-conspirators used the pileus to signify the end of Caesar's dictatorship and a return to a Republican system of government. The pileus was adopted as a popular symbol of freedom during the French Revolution and was also depicted on some early U.S. coins. RB89529. Bronze dupondius, RIC I 137 (R), BnF III 263 var.

Lucius Verus, 7 March 161 - February 169 A.D.

Commodus, March or April 177 - 31 December 192 A.D.
Felicitas was the goddess of good luck and success. She was a prominent symbol of wealth and prosperity and, during the Empire, she played an important role in Rome's state religion. Since it was considered the duty of the emperor to promote public happiness, almost every emperor struck coins dedicated to Felicitas. RS92466. Silver denarius, RIC III 65, BMCRE IV 111, RSC II 905, Hunter II -, SRCV II -, Choice gVF, nice portrait, dark old collection toning, flow lines, edge cracks, weight 2.611 g, maximum diameter 17.1 mm, die axis 180o, Rome mint, 183 A.D.; obverse M COMMODVS ANTON AVG PIVS, laureate head right; reverse TR P VIII IMP VI COS IIII P P, Providentia standing slightly left, head left, wand in right hand held over globe at feet on left, long scepter vertical in left; from the Errett Bishop Collection; $185.00 (€162.80)
Augustus, 16 January 27 B.C. - 19 August 14 A.D.
The wreath on the reverse is the corona civica, the oak wreath awarded to Roman citizens ex senatus consulto (by special decree of the Senate) for saving the life of another citizen by slaying an enemy in battle. It became a prerogative for Roman emperors to be awarded the Civic Crown, originating with Augustus, who was awarded it in 27 B.C. for saving the lives of citizens by ending the series of civil wars. SL89503. Orichalcum dupondius, RIC I 347 (R2), BMCRE I 197, BnF I 311, Cohen I 440, SRCV I 1667, NGC VF, strike 4/5, surface 2/5 (2490381-002), weight 11.903 g, maximum diameter 26.9 mm, die axis 0o, Rome mint, moneyer P.

Caracalla, 28 January 198 - 8 April 217 A.D.
The ancients did not all agree on the attributes of Serapis. A passage in Tacitus affirms that many recognized in this god, Aesculapius, imputing healing to his intervention; some thought him identical with Osiris, the oldest deity of the Egyptians; others regarded him as Jupiter, possessing universal power; but by most he was believed to be the same as Pluto, the "gloomy" Dis Pater of the infernal regions. The general impression of the ancients seems to have been that by Serapis, was to be understood the beginning and foundation of things. Julian II consulted the oracle of Apollo for the purpose of learning whether Pluto and Serapis were different gods; and he received for an answer that Jupiter-Serapis and Pluto were one and the same divinity. RB92485. Copper as, RIC IV 505 (S); Cohen IV 214; BMCRE V p. 478, 257; SRCV II -, VF, nice portrait, dark patina, scratches encrustations, weight 9.619 g, maximum diameter 25.5 mm, die axis 0o, Rome mint, 213 A.D.; obverse ANTONINVS PIVS AVG BRIT, laureate head right; reverse P M TR P XVI COS IIII P P, Serapis standing slightly left, head left, draped, kalathos on head, raising right hand with fingers spread, transverse scepter in left hand, S - C (senatus consulto) flanking below center; from the Errett Bishop Collection; very scarce; $160.00 (€140.80)
"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)
