GIOVARDI VICTORIO has written:

'ACTA PASSIONIS & TRANSLATIONIS SANCTORUM MARTYRUM MERCURII'

The days of the week in Latin are:

Dies Solis - Sunday

Dies Lunae - Monday

Dies Martis - Tuesday

Dies Mercurii - Wednesday

Dies Jovis - Thursday

Dies Veneris - Friday

Dies Saturni - Saturday

Wednesday is the day of the week between Tuesday and Thursday. The name is a calque of the Latin dies Mercurii "day of Mercury", reflecting the fact that the Germanic god Woden during the Roman era was interpreted as Germanic Mercury.

The Spanish word for "Wednesday," miércoles, comes from the Latin phrase Mercurii dies ("day of Mercury"). The name dates from the early years of the Roman Empire, when the 7-day week was adopted. Previously the Romans had used an 8-day week, with the days being identified by the letters A through H.
