"Bourdichon's atelier," Sido continued, "was probably actually in the Chateau de Plessis-lez-Tours, about 17 miles along the Loire River from Amboise. Then, studying the paintings in this Book of Hours we postulated that the artist was not Bourdichon himself. Our thesis is that he was a sailor/adventurer from a noble Breton family, who -- beginning in late Spring in order to fish for Cod -- sailed to the Grand Banks of Newfoundland. It was not unusual to bring artists aboard to make maps and document the landscape. In the Winter, the Master of the Music Box Book of Hours worked as an illuminator in Jean Bourdichon's studio, where into gridded spaces created by a scribe, he outlined the designs he had sketched, and -- before they were painted -- inlayed the gold."
