Marie was still in the very bloom of life, having only just attained her twenty-fourth year; nor could the King have forgotten that when, some time previously, her portrait had been forwarded to the French Court together with that of the Spanish Infanta, Gabrielle d'Estrees, then in the full splendour of her own surpassing loveliness, had exclaimed as she examined them: "I should fear nothing from the Spaniard, but the Florentine is dangerous." From whatever impulse he might act, however, it is certain that after the departure of the favourite, Henry publicly expressed his perfect satisfaction with the marriage which he had been induced to contract,[97] and lost no time in issuing his commands for the reception of his expected bride.
The Duc de Bellegarde, Grand Equerry of France, had reached Livorno on the 20th of September, accompanied by forty French nobles, all alike eager, by the magnificence of their appearance and the chivalry of their deportment, to uphold the honour of their royal master.

Seven days subsequently, he entered Florence, where he delivered his credentials to the Grand Duke, having been previously joined by Antonio de Medicis with a great train of Florentine cavaliers who had been sent to meet him; and the same evening he had an interview with his new sovereign, to whom he presented the letters with which he had been entrusted by the King.[98] On the 4th of October, the Cardinal Aldobrandini, the nephew and legate of the Pope, who had already been preceded by the Duke of Mantua and the Venetian Ambassador, arrived in his turn at Florence, in order to perform the ceremony of the royal marriage.

His Eminence was received at the gate of the city by the Grand Duke in person, and made his entry on horseback under a canopy supported by eight young Florentine nobles, preceded by all the ecclesiastical and secular bodies; while immediately behind him followed sixteen prelates, and fifty gentlemen of the first families in the duchy bearing halberds.

On reaching the church, the Cardinal dismounted, and thence, after a brief prayer, he proceeded to the ducal palace.

At the conclusion of the magnificent repast which awaited him, the legate, in the presence of his royal host, of the Dukes of Mantua and Bracciano, the Princes Juan and Antonio de Medicis, and the Sieur de Bellegarde, announced to the young Queen the entire satisfaction of the Sovereign-Pontiff at the union upon which he was about to pronounce a blessing: to which assurance she replied with grace and dignity.
On the morrow a high mass was celebrated by the Cardinal in the presence of the whole Court; and during its solemnization he was seated under a canopy of cloth of gold at the right-hand side of the altar, where a chair had been prepared for him upon a platform raised three steps above the floor.
