moon's _complete_ revolution, viz., her return to a certain position at the precise time at which she set out therefrom, an event which takes place but once in _fifty years_: in other words, if the moon be on the equator, say, on the first day of February, and calculating twenty-nine days to the month, or twelve lunations to the year, a cycle of fifty years, or "seven Sabbaths of years," must elapse ere she will again be in that position on the same day. HIPPARCHUS. Limehouse, March 31. 1851. _Arms of Isle of Man._--The arms of the Isle of Man are gules, three legs conjoined in the fess point, &c. &c. or. These arms were stamped on the old halfpence of the island, and we may well call them the current coin. In an old edition of the _Mythology of Natalis_ {374} _Comus_, Patavii, 1637, small 4to., at page 278., I find an Icon of Triptolemus sent by Ceres in a chariot drawn by serpents, hovering in the clouds over what I suppose to be Sicily, or Trinacria; and on a representation of a city below the chariot occurs the very same form of coin, the three legs conjoined, with the addition of three ears of corn. This seems to me to be a curious coincidence. MERVINIENSIS. _Doctrine of the Resurrection._--Can any of your readers inform me of any traces of the doctrine of the Resurrection to be found in authors anterior to the Christian era? The following passage from Diogenes Laertius is quoted in St. John's _Manners and Customs of Ancient Greece_, vol. i. p. 355.: "[Greek: Kai anabiosesthai, kata tous Magous, phesi (theopompos), tous anthropous, kai esesthai athanatous.]" How far does the statement in this passage involve the idea of a _bodily_ resurrection? I fancy the doctrine is not countenanced by any of the apparitions in the poetical Hades of Virgil, or of other poets. ZETETICUS. _National Debts._--Is there any published work descriptive of the origin of the foundation of a "National Debt" in Florence so early as the year 1344, when the state, owing a sum of money, created a "Mount or Bank," the shares in which were transferable, like our stocks? It is not mentioned in Niccolo Machiavelli's _History of Florence_; but I have a note of the fact, without a reference to the authority. Is there any precedent prior to the foundation of our National Debt? F. E. M. _Leicester's Commonwealth._--Are the real authors of _Leicester's Commonwealth_, and the poetical tract generally found with it, _Leicester's Ghost_, known? According to Dodd's _Church History_, the first is _erroneously_ attributed to Robert Parsons the Jesuit. EDWARD F. RIMBAULT. * * * * * Replies. HISTOIRE DES SEVARAMBES. (Vol. iii., pp. 4. 72. 147.)
