Newton began by dating the baptism of Christ in AD 29 during the 15th year of Tiberius Caesar (Luke 3:1, 21).
He then cited evidence for a total of five (rather than four) passovers during the ministry, implying an AD 34 crucifixion.
Yet long after the facts had been published, when the [page vi] Head Master of a certain considerable Midland school asked for information as to its origin and history and was told that there was evidence of its existence in the days of Edward the Confessor, he responded by entreating me not to try and make a fool of him. Rounded periods, far-fetched conceits and out-of-the-way expressions gained applause in the schools, but they tended to destroy real oratory and hastened rather than hindered the decadence of public life. 97-108, in a letter to a friend, sending him a copy of a speech he made to his fellow-citizens of Como on giving them a public library, incidentally mentions that, instead of a gladiatorial show, he had established exhibitions (annuos sumptus in alimenta ingenuorum pollicebamur), since to make any one willingly undergo the tedium and labour of education, not only premiums, but endowments were required. 69-79, was the author of a system of endowed schools, being, according to Suetonius, 'the first to endow Latin and Greek rhetoricians with a stipend of 100,000 sesterces' [= 800, says Mr. 'I was put to school to get learning of which I knew not what use there was; and yet, if slow to learn I was flogged.

For these last items he is only repeating Greek formulæ and does not represent actual Roman practice. 305-306, with vicarious liberality, ordered the municipality of Augustodunum (Autun) to pay Eumenius, the master of the rhetoric school, from the public funds a salary of 600,000 sesterces (4800 a year). According to Augustine and others, he also by edict prohibited Christians from teaching in the schools; but as there is no record of any such edict forthcoming, this accusation must be received with the caution due to all the statements made by early Christian apologists about their opponents. 376, went even further in extending the interference of the central authority, charging the Praetorian Prefect of Gaul that 'in all towns which are called metropolis', equivalent in modern parlance to county boroughs, 'notable professors should be elected', and paid according to a scale of salaries laid down, viz.
Apparently no one has questioned his claim, but Newton obtained similar results two centuries earlier.
Researchers from Newton to Schaefer have essentially agreed on dates of lunar visibility, but not on the resultant crucifixion date.
They did not have the benefit of cheap, off the shelf, mass produced batteries. Bronze is a relatively hard alloy of copper and tin, better suited for the purpose than the much softer copper enabling improved durability of the weapons and the ability to hold a cutting edge.
For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn't until the twentieth century that new applications created the demand that made the battery a commodity item. The use of bronze for tools and weapons gradually spread to the rest of the World until it was eventually superceded by the much harder iron.
