V. It was on the first of October, 1638, that Grotius went to solicit the King in favour of those who had insulted him:  the Court was then in great joy for the happy birth of the Dauphin[356], who came into the world on the 5th of September.  The Swedish Ambassador saw the King, the Queen, and the Dauphin, and made them his compliments such as the occasion required, though it was not the principal object of his journey as he could not have received orders on the subject.  He recommended to the King the affairs of the Duke of Weymar, whom the Imperialists were going to attack with a force infinitely superior.  His Majesty promised to augment that Prince’s army as much as his other affairs would permit.  Grotius having represented of what advantage an extraordinary gratification might be to the good of affairs in Germany, the King exclaimed against the great expences with which he was overpowered, but gave hopes that he would advance a sum of money beyond what he engaged to furnish.  November 10, 1638[357], Grotius had another audience of the King, to entreat him not to abandon the Duke of Weymar in his present extremity:  he assured his Majesty that he had precise orders to recommend to him the affairs of that Prince with the same zeal as those of Sweden.  The King contented himself with giving a vague answer, which did not satisfy the Ambassador.  December 4[358], he waited on the King and Queen to compliment them, by order of the Queen of Sweden, on the birth of the Dauphin.  A letter written by him next day to Queen Christina relates all that passed at these audiences.  After observing that he had publicly expressed his joy for the desired birth of the young Prince by bonfires, entertainments, and distributions of wine to all the neighbourhood, he tells her that he had seen the King, whom he informed of the entertainments made in Sweden on occasion of the birth of the Dauphin of France; that he observed to his Majesty, if it were true, as the Ancients believed, that names were not given by chance, one ought to prognosticate great things of the Dauphin [Anglice Dolphin]; that the signs which surrounded the Constellation bearing his name, denote the most happy presages; that it was surrounded by the Eagle, Pegasus, Sagittarius, Aquarius, and the Swan; that the Eagle denoted a superior genius; Pegasus presaged that he would be powerful in cavalry, Sagittarius in infantry, and Aquarius in naval force:  the Swan signified that his great actions would be celebrated by poets, historians, and orators:  that the nine stars in the sign of the Dolphin denoted, according to astrologers, the nine Muses, who were to render the Prince illustrious and receive lustre from him:  that the Dolphin being near the Equator, signified that the King’s justice would be hereditary to his son; that naturalists had remarked three properties in the Dolphin, which ought to be considered as happy presages of what the Dauphin of France would be:  that it loved men; that it came quickly to maturity; and had much activity.
