Can anyone translate this old headstone from Germany?

Question

This is the text that I can see. Hopefully you will be able to view the image if I can add it.

I've tried various translation sites but nothing is really working. I could makes guesses but I'm very curious exactly what it says and means. V's could be U's and this headstone is located in Memmingen, Stadtkreis Memmingen, Bavaria (Bayern), Germany.

Here is a link to the image.

Answer 1

This headstone is in Latin. Your transcription is quite good, but the text includes several abbreviations, which I've filled in below with brackets:

D[EO] O[PTIMO] M[AXIMO]

MORTALIT[ATIS] SUAE MEMOR
ANDREAS SEYLER
REIP[UBLICAE] MEMMING[EN] SENAT[OR]
ET
PHARMACOP[OLA]
BIPONT[I] NAT[US]
MDCCVI DIE XXIV APR[ILIS]
MONUMENT[UM] HOC SEPULCRALE
PARAVIT
SIBI POSTERISQUE SUIS
MDCCLXXII

Here's a literal translation:

To God, most good, most great

Mindful of his mortality, Andreas Seyler, a senator of the republic of Memmingen and a pharmacist, born at Bipontum [=Zweibrücken] on April 24, 1706, prepared this funerary monument for himself and for his descendents, in 1772.
